A golf club head maintains a low weight of a face part, keeps the resilience property of the face part in the rule conformity range, and prevents the resilience performance from decreasing even when a ball is hit by a face part deviating from the sweet spot. The golf club head has a sole, a crown, a toe, and a heel and comprises a face part formed of a metallic material. The face part comprising: an outer peripheral portion; a thick-walled portion having a wall thickness greater than that of the outer peripheral portion, the wall thickness of the thick-walled portion being greatest in a central portion of the face part and decreasing gradually from the central portion toward the outer peripheral portion, wherein the thick-walled portion is positioned over a region having a shape formed by depressing a circular or elliptical shape from two opposite sides thereof, the first depression on the toe side being directed orthogonal in the sole direction, and the second depression on the heel side being directed orthogonal in the crown direction; and at least two thin-walled portions having a wall thickness less than that of the outer peripheral portion, the thin-walled portions being positioned over a region surrounded by the two opposite sides of the circular or elliptical shape and the depressions. |
