The main body 1 is formed in an integrally formed manner, and has a striking plate and a receiving groove 1〇2 provided inside the striking plate 101 and having an opening upward. The composite material layer 2 is filled in the accommodating tank 2. Although the above-described golf head utilizes the arrangement of the composite material layer 2, the weight of the region corresponding to the body 1 can be reduced to lower the center of gravity, and the characteristics of the composite material layer 2 can be used to produce better impact elasticity. However, since the pad 1〇1 is integrally coupled to the main body ,, and the composite material layer 2 is in a cutting manner and is separated from the striking plate 1〇1, only the striking plate is struck. The 101 is in contact with the ball, and the characteristics of the layer a of the composite material material 2 cannot be fully utilized, so that the elasticity of the composite material layer 2 can be poor. As shown in Fig. 2, another golf club head includes a body 3, a composite material layer 4 filled in the interior of the body 1, and a pad 5 fixed to the body 3 by welding. The body 3 is made of a metal material and has a front side 3〇1 and a recess 302 which is recessed toward the inside by the front side 3〇1. The composite material layer 4 is filled in the recess 2 The pad 5 is made of a metal material and is formed integrally with the body, and has a 1286945 facing surface 501 corresponding to the front side 301. The striking plate 5 of the golf club head is welded and integrated with the main body 3, and the composite material layer 4 is still filled and separated from the striking plate 5, so when hitting, the The elasticity provided by the striking plate $ in contact with the ball is also poor, and the characteristics of the composite layer 4 cannot be fully utilized. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a golf club head that is simple in construction and that produces better ballistic elasticity. Another object of the present invention is to provide a method of making a golf club head that produces a better ball-spinning elasticity by a simple process.

The toric surface has a first surface opposite to the bottom surface of the groove and a surface opposite to the 1286945 The (four) plate is provided with the composite material (four) (four) with respect to the second surface of the joint surface. The second bonding layer is a method for manufacturing the invention, and the bottom surface unit of the body is fixed on the bottom surface unit. The method includes the following steps: (4) preparing a book=made of a metal material, And having a front side and a groove recessed by the front side /=, the groove is defined by a pair of groove bottom surfaces of the front side of the groove extending from the periphery of the groove bottom surface to the groove wall surface of the front side ( B) preparing a striking plate unit having a contour shape corresponding to the groove, wherein the striking plate is fixed to a striking plate to fix a composite material layer with a first bonding layer. (C) fixing the pad unit in a recess of the body with a second glue layer. Thereby, the golf club of the present invention utilizes the action of the pad of the pad unit to separate from the body and the arrangement of the composite layer, which can produce better ballistic elasticity when the pad is hit. Achieve the goal of reducing the center of gravity. The steps of the method of the present invention are relatively simple, and the manufacturing cost can be reduced. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be described in the following detailed description of a preferred embodiment with reference to the drawings. 〉The presentation of the moon Chu. As shown in FIG. 3 and FIG. 4, a preferred embodiment of the golf club head of the present invention includes a body 10, a pad unit 20 mounted in the body 10, and a pad unit 20 fixed thereto. The second glue layer 1286945 on the body 1〇 is made of metal (4) and is cut by a job casting method, and has a front side U and a groove 12 from the front side to the inner side (four) The groove 12 is defined by a pair of groove bottom surfaces (2) which should be the front side u and a peripheral edge of the groove bottom surface 121 extending to the front side core groove wall in. The pad unit 20 is disposed on the body 1 The groove 12 has a thickness and a contour shape corresponding to the groove 12, and has a pad 21 corresponding to the front side η, a pair of composite layers 22 corresponding to the groove bottom surface (2), and a composite plate between the pad 2i and the pad 2i The first glue layer between the material layers 22 is made of titanium, high _, non-recorded steel, etc., and has a pair of striking faces 211 which should be front side u, and one of the striking faces 2 ι a joint surface 212 disposed on the back surface opposite to the bottom surface 121 of the groove and extending from the striking surface a circumferential surface 213 of the peripheral surface of the joint surface 212, the front side surface η can engrave a plurality of lateral grooves 214. The annular surface 213 is opposite to the groove wall surface 122. The material layer 22 is made of carbon fiber, glass fiber, and carat fiber. The fiber material is mixed with the thermosetting epoxy resin, and has a first surface for the bottom surface 121 of the groove, and a second surface opposite to the first surface 221 and opposite to the bonding surface 212. 222. The first knee layer 23 is coated with a thermosetting epoxy resin in a web 231 for the baffle 21 to be consolidated with the composite layer 23.
