Abstract
A golf club head capable of enhancing a moment of inertia and improving a directional stability of a ball. In the golf club head, a flange is formed on a peripheral portion of a back side of a head body, and projects rearwardly from the head body to thereby form a cavity in the back side, and a weight member, made of a material larger in specific gravity than the head body is secured within a recessed formed in outer peripheral surface of the flange. The weight is positioned at a top and a sole side of the head body so as to evenly distribute the weight over the outer peripheral surface of the flange.
