Abstract:
The golf club set according to the present invention is a golf club set constituted by a plurality of numbered golf clubs with different loft angles. In each of the golf, a crown portion has a main body portion that connects to the sole portion and a raised portion that rises to form a step from the main body portion and extends in a toe-heel direction along a boundary with the face portion. In at least one pair of a lower numbered golf club and a higher numbered golf club, among the plurality of golf clubs included in the golf club set, a length of the step in a face-back direction along a perpendicular plane that passes through a sweet spot and a center of gravity of the golf club head is longer in the lower numbered golf club than in the higher numbered golf club.
