Abstract
A golf club head includes a striking face having a plurality of grooves formed therein. At least one groove includes a first curved side surface, a second curved side surface opposite to the first curved side surface, and a bottom surface connecting the first and the second curved side surfaces. As viewed in the longitudinal direction of the at least one groove, the first and the second curved surfaces respectively have first and second involute profiles. A distance measured between the first and the second curved surfaces continuously increases from the bottom surface to the striking face.
