ABSTRACT:
Disclosed is a golf club head which comprises: a head body constituted by a core material coated with a layer of fiber-reinforced resin, such as carbon-fiber-reinforced resin, glass-fiber-reinforced resin, or the like; and a sole plate attached to a sole portion of the head body, the sole plate having a protrusion being buried in the head body and projecting outward beyond a peripheral edge of the sole plate; whereby the protrusion may bite into the head body even if a large force is exerted to a head by a shock at the time of a shot so that the sole plate is positively prevented from peeling off from the head body, and the weight of the protrusion portion is added to the periphery of the head body to thereby make the moment of inertia of the head high.
