Abstract
A golf club head includes a face member having a ball-striking face and an oval thick portion positioned in a central portion of the ball-striking face. The oval thick portion has an oval shape having recesses formed by recessing both sides in a major axis direction in an arc-shaped fashion. The recesses are directed to a toe-side upper portion and a heel-side lower portion. The thickness of the thick portion becomes thickest at a central portion and is gradually reduced from the central portion towards the periphery. The face member is formed such that a portion outside the thick portion is thinner than the thick portion. An occupancy rate of the oval thick portion in the ball-striking face is in a range of 25 to 45%.
