Abstract
A golf club head having a hollow construction includes a face part having a ball-impacting surface and a first main rib and a second main rib disposed on the inner surface of the face part. The first main rib extends from a crown side to a sole side, and the second main rib extends from a hosel side to a toe-side part of the sole side, the first and second main ribs intersecting each other. The material thickness on a toe side of the face part, with the first main rib being the boundary, is formed so as to be thinner than the material thickness on a heel side of the face part.
