Abstract
A golf club head comprises a hollow body having a cavity, a plurality of rib-like walls provided on the inner surface of the hollow body so as to extend backward from a position near the face portion, and a sound bar disposed behind the face portion so as to extend along the back face of the face portion. A method of making a golf club head comprises making a wax model of the hollow main body having an opening, wherein in order to prevent deformation of the wax model during making a casting mold, the wax model is provided with a brace which extends across the opening and protruding walls which are disposed on the inner surface of the wax model and extend backwards from the opening.
