A golf club head includes a recessed part on the external surface of a head main body, and a weight member mounted in this recessed part and formed of a material having a specific gravity greater than that of the head main body. This golf club head has a first addition member mounted on and abutting the external side of the weight member. A base of this first addition member is a resin or a rubber. The head has a second addition member mounted on and abutting the external side of the first addition member. This second addition member is formed of a metal having a specific gravity greater than that of the first addition member and smaller than that of the weight member. Therefore, the joint strength between the head main body and the weight member can be enhanced.
