TECHNICAL FIELD [0001] The present invention relates to a cooling suit configured to cool a wearer's body by causing outside air to flow along the wearer's body parallelly thereto. BACKGROUND ART [0002] It is possible to regard a human as an extremely inefficient working device which ingests food to conduct life support activities, pieces of work, and the like, and to generate heat commensurately therewith. Due to the inefficiency, most of caloric intake is turned into heat, thereby requiring radiation of a large amount of heat commensurating with a then quantity of work in order to keep a normal body temperature. To this end, humans each possesses a physiological ability for cooling his/her body by virtue of perspiration. Namely, there is determined a physiologically required quantity of heat radiation commensurately with a quantity of work, and perspiration is exuded commensurately therewith, in a manner to attain heat radiation which is most suitable for the then situation of him/her when the perspiration is fully evaporated. Naturally, the amount of perspiration commensurating with the quantity of heat radiation will not be unequivocally calculated by his/her brain. Nonetheless, drastically raised body temperatures lead to large amounts of perspiration to be continuously exuded, and resultingly lowered body temperatures lead to reduced amounts of perspiration, so that the body is not excessively cooled. As such, there is resultingly exuded an amount of perspiration commensurately with a required quantity of heat radiation. [0003] However, it becomes impossible to obtain a required quantity of heat radiation when vaporization of perspiration is disabled depending on conditions of temperature, humidity, presence/absence of airstreams, quantity of work, and the like, such that perspiration is continuously and uselessly exuded in a liquid state without vaporization, thereby causing not only uncomfortableness but also physiological damages. As such, there is required aid of a cooling suit. Among cooling suits, the cooling suit (hereinafter also called "air-flow type cooling suit") of a type configured to cool a wearer's body by causing outside air to flow along the wearer's body parallelly thereto, cools the wearer's body by utilizing outside air without using a cooling device such as a compressor, thereby enabling achievement of mild cooling of the wearer's body at a reduced power consumption. [0004] Patent-related reference 1: International Publication WO 02/067708 pamphlet DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention [0005] Incidentally, conventional air-flow type cooling suits are each capable of evaporating perspiration exuded during conduction of a normal work of a wearer, thereby enabling the wearer of the cooling suit to be appropriately cooled. However, it has been impossible to sufficiently evaporate the exuded perspiration, when the wearer exuded a large amount of perspiration due to a work in a high temperature environment, a hard work, or the like. Namely, it has been impossible to use the conventional air-flow type cooling suits under such severe usage environments. Further, the conventional air-flow type cooling suits are each provided with spacers between the cooling suit and an undergarment so as to ensure an airflow passage. This has caused the conventional air-flow type cooling suits to be complicated in configuration. [0006] Further, cooling suits to be used in a situation that a large amount of perspiration is exuded, are to be desirably easily washable, since such cooling suits are stained with perspiration. [0007] The present invention has been made under the above-described circumstances, and it is therefore an object of the present invention to provide a cooling suit having a simple structure and capable of assuredly evaporating a large amount of perspiration. [0008] In addition to the above object, it is another object of the present invention to provide a cooling suit which is easily washable. Means for Solving the Problem [0009] To achieve the object, the invention recited in claim 1 resides in a cooling suit to be worn on a wearer, comprising: at least one air inlet configured to introduce outside air; at least one parallel airstream generation means for introducing the outside air through the or each air inlet to generate parallel airstreams which are substantially parallel to the wearer's body; a guide sheet simultaneously serving as a garment and for guiding the parallel airstreams generated by the or each parallel airstream generation means, parallelly to the wearer's body; at least one air exit portion configured to discharge the parallel airstreams to the exterior; and electric-power source means for supplying electric power to the or each parallel airstream generation means; wherein the or each parallel airstream generation means cooperatively blows air of a total amount of about 5 m.sup.3/H to 500 m.sup.3/H into between the guide sheet and an undergarment or wearer's body to cause positive pressures between the guide sheet and the undergarment or wearer's body to thereby produce an air flow space therebetween, and the or each parallel airstream generation means causes the blown air to flow through the air flow space to thereby discharge moisture due to perspiration to the exterior and to thereby constantly feed fresh outside air into the air flow space, thereby largely intensifying conditions where perspiration can be evaporated. Effect of the Invention [0010] The cooling suit according to the present invention is capable of causing a large amount of air to flow between an undergarment or wearer's body and a guide sheet so as to largely extend an effective area under the influence of a physiological cooling ability of the wearer to thereby cool the wearer's body.
