Abstract: Provided is a golf club head which produces an improved hitting sound obtained without impairing the appearance of the sole section. A golf club head having a hollow portion (i) formed therein has a sole portion (5) which forms the bottom surface of the head. The sole portion (5) includes a thin-wall portion (8) and a thick-wall portion (9) which has a greater thickness than the thin-wall portion (8). The golf club head is characterized in that a portion of the inner surface of the thick-wall portion (9), the portion facing the hollow section, has a rib (10) secured to the portion by welding.
