Abstract
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.
