A metallic frame-shaped iron head body is composed of a heel section, a toe section, an upper edge section connecting superior ends of the heel section and of the toe section, and a sole section. On a front face of the head body, a metallic thin-walled face section having a high coefficient of restitution is provided. The head body includes rear wall sections spaced apart from the face section and extending upward from a rear end of the sole section. A reinforced fiber member is placed in an area surrounded by the face section, the sole section, and the rear wall sections. This reinforced fiber member abuts on a back of the face section to form a closed hollow void section, and apart of a back of the reinforced fiber member is supported on the rear wall sections.

To provide a golf club head in which a sole portion has a high rigidity. A weight material is mounted near a central part of the sole portion in the fore-to-aft direction, and a rib extends in the toe-to-heel direction. Since the sole portion has high rigidity in the toe-to-heel direction, there is less deformation of the head in the toe-to-heel direction when hitting the ball, thereby suppressing the vibration of the sole portion. An elastic body is filled in a recess portion and closely contacted with the weight material, whereby the vibration of the sole portion is absorbed by the elastic body.

A golf club head has a face portion, a crown portion, a sole portion, a side portion and a hosel portion. Each portion is made of titanium or a titanium alloy.

The face portion, the crown portion and the sole portion are molded separately from one another. The face portion, the crown portion, the sole portion and the side portion are welded integrally so as to form a golf club head. The Young's modulus of the crown portion is lower than any Young's modulus of the face portion, the sole portion, the side portion and the hosel portion.
