Abstract
This invention provides a golf club head comprising a head main body, a face plate fixed to a front surface side of the head main body to form a face surface, a cavity portion formed in the head main body and open to a face plate side, and a viscoelastic body inserted in a compressed state in a space formed by the cavity portion and the face plate. An end face on the face plate side of a circumferential wall defining the cavity portion comprises a contacting portion contacting with a rear surface of the face plate, and a non-contacting portion spaced apart from the rear surface of the face plate to form a gap communicating with the cavity portion between the non-contacting portion and the rear surface of the face plate.
