Abstract
A head body of a golf club head has a hollow portion defined by an outer wall. An opening portion is provided in a part of the head body. A small tungsten alloy piece having a shape fittable to the opening portion so as to cover the opening portion is fixedly attached to the opening portion by welding. The golf club head defines the opening portion in a part of the metal head body and has the small tungsten alloy piece fitted and joined to the opening portion by welding so that the golf club head can be reduced in weight because of provision of the hollow portion. Since the small tungsten alloy piece is joined to the opening portion by welding, difficult plastic forming is not required particularly, and the weight can be adjusted easily and accurately.
