Abstract
A golf club head has a hollow therein and a head volume of not less than 350 cc. The head comprises a head main body and a substantially cup-shaped face member which are united with each other. The face member integrally includes a face portion having a club face for hitting a ball, and a turnback extending backwardly of the head from a peripheral edge of the club face. The inner surface of the face member is provided with a groove extending along the boundary of the turnback with the face portion. The face member is a press-formed part whose turnback is bent by press working.
