A head includes a face part, a sole part, and a hosel part. The face part includes a hitting surface and a face back surface. A plurality of score lines are formed on the hitting surface. One or two or more back grooves are formed on the face back surface. With reference to a face center, the face part is divided into four regions: a toe upper region; a toe lower region; a heel upper region; and a heel lower region, and back-groove projected areas of at least two regions out of the four regions are different from each other. Back-groove occupation ratios of at least two regions out of the four regions may be different from each other.
