CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 11/321,438, filed on Dec. 29, 2005, and abandoned as of the filing date of this application. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a golf club head, more particularly to a golf club head with an improved rebound capability. [0004] 2. Description of the Related Art [0005] Referring to FIG. 1, a conventional golf club head includes a head body 1 and a composite portion 2. The head body 1 is formed integrally by molding, and includes a striking portion 101 and a receiving space 102. The composite portion 2 is filled in the receiving space 102. [0006] Since the striking portion 101 is integrated with the remainder of the head body 1, and since the composite portion 2 is filled in the receiving space 102, rather than being formed as a part of the striking portion 101, the resilient property of the composite portion 2 cannot be effectively imparted to the striking portion 101 when the striking portion 101 strikes a golf ball. Therefore, the rebound capability of the conventional golf club head is inferior. [0007] Referring to FIG. 2, another conventional golf club head includes ahead body 3, a striking plate 5 connected to the head body 3 by welding so as to define a receiving space 302, and a composite portion 4 filled into the receiving space 302. The head body 3 is made of metal, and has a front face 301. The striking plate 5 is made of metal, and has a striking face 501 flush with the front face 301 of the main body 3. [0008] Since the striking plate 5 is made of metal, and since the composite portion 4 is filled in the receiving space 302, rather than being formed as a part of the striking plate 5, this prior art also encounters the same drawback as that of the prior art shown in FIG. 1. [0009] U.S. Pat. No. 6,743,117 discloses a golf club head with face inserts. A strike face insert, a dampening insert, and a composite back insert are received in a cavity sequentially. The strike face insert is preferably made of stainless steel, and has a thickness preferably ranging from about 0.07 inch to about 0.11 inch (i.e., from about 1.78 mm to about 2.79 mm). The dampening insert is used for absorbing vibration energy and for reducing noise when a golf ball strikes on the golf club head. The dampening insert is formed preferably of lead, and has a thickness ranging from about 0.005 inch to about 0.025 inch (i.e., from about 0.13 mm to about 0.64 mm), which is remarkably smaller than that of the strike face insert. The composite back insert is preferably made of carbon graphite material, and has a thickness preferably ranging from about 0.02 inch to about 0.04 inch (i.e., from about 0.51 mm to 1.02 mm). The composite back insert having such small thickness has high flexibility and less stiffness and is thus used for dampening. As the composite back insert is deformable and can absorb striking energy, a ball cannot be stricken with a maximum striking energy. [0010] U.S. Pat. No. 6,875,124 discloses an iron type golf club head. A front face of the golf club head has a thickness ranging from about 0.06 inch to about 0.12 inch (i.e., from about 1.5 mm to about 3.0 mm). A composite insert of the golf club head comprises one or more layers of a light, flexible material like nylon, reinforced plastic or a carbon graphite composite sheet. The composite insert functions to dampen out unwanted vibrations, adjust weight, or provide structural stability. The weight ratio of the composite insert is not specified. [0011] U.S. Pat. No. 4,792,140 discloses an iron type golf club head. A resin member of the golf club head is preferably made of synthetic resin such as ABS, ionomer, polycarbonate. [0012] In the conventional golf club heads, a striking member made of titanium has a density of about 4.7 g/cm.sup.3, a striking member made of iron has a density of about 7.7 g/cm.sup.3, a striking member made of steel has a density of about 9.0 g/cm.sup.3, a striking member made of wood has a density of about 1.5 g/cm.sup.3, and a striking member made of a plastic material, such as nylon, ABS, or the like, has a density of about 1.8 g/cm.sup.3. When the striking member is made of pure metallic material, such as titanium, iron, or steel, the overall weight of the golf club head is too heavy. On the other hand, when the striking member is made of plastic or wood, the strength of the golf club head is insufficient, and thus the thickness thereof should be increased. SUMMARY OF THE INVENTION [0013] Therefore, the object of the present invention is to provide a golf club head which possesses improved rebound capability. [0014] Accordingly, the golf club head of this invention includes: a head body having a front face and a recess formed in the front face; a striking member fitted in the recess and having a striking plate flush with the front face and having a thickness ranging from 0.6 mm to 1.4 mm, a carbon-fibre composite layer backing the striking plate and having a thickness ranging from 3.0 mm to 5.0 mm, and a first adhesive layer for adhering the striking plate to the composite layer; and a second adhesive layer to adhere the composite layer of the striking member to the head body. The weight ratio of the composite layer to the striking member ranges from 50% to 85%.
