Abstract
A golf club head includes a metal head body and a face plate made of fiber reinforced resin and fitted to a recess formed in a face portion of the metal head body. A support pin is inserted into the main body from a back portion thereof, threadingly engaged with the face plate and prevented from being exposed on a hitting surface of the face plate. A back portion of the head body is formed with a concave whose outer configuration is substantially the same as that of the face plate. The concave is located at a position of the back portion corresponding to a position of the face plate on the face portion. A central recess is further formed in the back portion within the concave depending on a position of a sweet spot. A flexible member is attached to the central recess. It is possible to reliably prevent the accidental separation of the face plate from the head body, and the damage and/or breakage of the face plate due to the difference in stiffness between the face plate and the metal head body.
