In the figures, 1 is a head body made of a metal material such as stainless steel, cast iron, or brass, and the ball is hit by the head body. In order for the surface portion 2 to exhibit a predetermined loft angle, it has a triangular cross-sectional shape, with the wall thickness increasing from the blade portion 1a at the edge to the sole surface portion 3 at the lower edge. Then, the ball hitting surface portion 2 of this head body 1
A recess 4 is formed over almost the entire surface of the back side in the ball hitting direction corresponding to , and a surface 4a of this recess 4 corresponding to the ball hitting surface 2 is flattened, so that the thickness of the ball hitting surface 2 made of the thin metal plate is flattened. Processing is performed so that the thickness is approximately equal. Further, reference numeral 5 in the figure denotes a fiber-reinforced member attached in close contact with the surface 4a corresponding to the ball-hitting surface 2 of the recess 4 formed on the back side of the head main body 1, and is made of a high elastic modulus material such as CFRP. By joining this fiber reinforced member 5 to the recess 4, the portion corresponding to the ball hitting surface of the head is made of metal plate and CFRP.
It is constructed to have a double composite laminated structure with high elastic modulus materials such as. In addition, 6 in the figure indicates the head main body 1
A back-up member made of a synthetic resin material is filled and formed in the recess 4 on the back side of the fiber reinforced member 5. After the fiber reinforced member 5 is joined to the recess 4, the synthetic resin material is filled into the recess 4 from the outside of the fiber reinforced member 5 and hardened. By applying this, the fiber reinforced member 5 is backed up to prevent it from falling off.

能にしている。The fiber reinforced member 5 may be made by laminating a plurality of reinforcing fibers in a multi-layered manner, for example, with a thickness corresponding to the desired weight reduction, and adding epoxy resin or An FRP board formed by impregnating an uncured synthetic resin liquid for matrix such as unsaturated polyester resin and curing semi-cured prepreg or wet type if necessary, or a thin hardened FRP board. A laminate is used in which multiple sheets are glued together. Furthermore, as for the types of reinforcing fibers, in addition to the single use of two-dimensionally woven or three-dimensionally woven carbon fibers, carbon fibers can also be used mainly with high modulus aromatic polyamide fibers, glass fibers, boron fibers, and silicon carbide. A suitable combination of fibers or alumina fibers is used, and the reinforcing fibers can be woven or knitted using cloth alone, a combination of cloth and roving, a mat alone, or a combination of other cloths. The reinforcement effect can be adjusted.
