Abstract
An iron-type golf club head comprises a face having a striking surface, a back surface, and a face thickness defined therebetween. The back surface is provided with a cavity cavity-forming portion dented toward the striking surface. The cavity cavity-forming portion is provided with a protuberance in which the face thickness is partially increased, and which extends in the top-bottom direction of the head. In the cross section of the face perpendicular to the striking surface and parallel to the toe-heel direction, the protuberance has: a ridge at which the face thickness is largest in the protuberance; and a pair of inclined surfaces extending from the ridge toward a toe side and heel side of the cavity cavity-forming portion while decreasing the face thickness.
