Abstract
An improved golf club head includes a metallic main body 1 having a face side section 2 providing a face side surface for shooting balls. A rearwardly opening gouge 3 is formed within the main body, extending to an end wall 3a provided by the face side section. An FRP plate 4 is inserted into the gouge and held against the end wall 3a by an open frame 5 which engages a circumferential portion of the plate 4. Presence of the light FRP plate in the face side region allows free weight assignment to other regions for ideal inertia moment adjustment and produces locally laminated face side construction in which thickness ratio of components can be adjusted for better feel at shooting.
