摘要 The invention concerns an arrangement for a golf club head, which can enhance the surface rigidity of the ball hitting surface of a face plate to extend the carry of the ball and to stabilize the direction of the hit ball. In the golf club head, a recessed portion is formed in the back portion of a head main body formed of metal with the peripheral edge portion thereof remaining unrecessed, and a support portion having a thickness smaller than the peripheral edge portion is provided integrally with the head main body in such a manner that it is interposed between the mutually facing inner walls of the recessed portion.
