安定させることが出来る効果がある。The present invention provides a golf club head that is covered with fiber-reinforced plastic except for the sole portion as described above, which is a three-dimensional fabric made of carbon fiber, glass fiber, aromatic polyamide fiber, etc. and impregnated with a matrix resin. A woven fabric main body portion formed to a predetermined thickness and a sag portion formed by removing at least a portion of the warp or weft yarns around the woven fabric body portion, and the woven fabric main portion of the three-dimensional fabric is attached to a club head. It is disposed over almost the entire surface of the face of the main body, and a sagging part is disposed around the face, embedded in the fiber-reinforced plastic that constitutes the club head main body, and integrally molded, so that the face part is continuous. Due to strong hits, the matrix resin between the laminated layers is destroyed, fibers are separated, and cranks that occur in the peripheral area connecting to the face, especially at the boundary with the upper part, can be prevented, and the life of the club head can be improved. Further, it has the effect of making it possible to improve the followability of a three-dimensional fabric with a molding die having high bending rigidity, thereby stabilizing the molding finish.
また、フェイス面の厚さ方向への繊維補強が可能となる
ため、フェイス部の剛性が高くなり、ボールの飛び特性
