Abstract
A golf club head of this invention includes a face portion, first and second interchangeable members, a first attachment portion from which the first and second interchangeable members are detachable, and a second attachment portion from which the first and second interchangeable members are detachable. The first interchangeable member is a reinforcing member that abuts against the rear surface of the face portion and restricts deformation of an abutment portion when the member is attached to the first attachment portion. The second interchangeable member is a member that does not abut against the rear surface of the face portion when the member is attached to the first attachment portion.
