The crown, the sole, and the hosel chamber include laminated layers of a fiber-reinforced resin. The crown includes at least one first rigidity control portion that partially extends in a toe-heel direction. The sole includes at least one second rigidity control portion that extends from a back surface side of the face toward a back end of the body. One of the first rigidity control portion and the second rigidity control portion decreases flexural rigidity in a face-back direction, and the other of the first rigidity control portion and the second rigidity control portion increases flexural rigidity in the face-back direction.
