Abstract
In a golf club set, a face plate made of a material that is lower in specific gravity and elastic modulus than that of a head body of each golf club, is mounted on a face portion of the head body. The thicknesses of the face plates of the golf clubs increase in the order of the golf clubs of large club numbers to those of small club numbers. Further, a through hole may be formed through the head body of each golf club to extend from a face portion thereof to a back portion thereof. In this case, the face plate is mounted on the face portion of the head body, while closing the through hole.
