A golf club head is disclosed, which is capable of setting a head center of gravity projected on a face surface in the vicinity of a face center even when a head thickness excluding a face portion is made uniform or a head volume is increased to a maximum. In this golf club head, in a three-dimensional coordinate axis with a face center set as an origin, a coordinate value of each most bulged position in a head body is specified, and a shape of the head body is brought close to that of symmetry in an upper-lower direction and, more preferably, to that of symmetry in upper-lower and right-left directions.
