To provide a golf club and a golf club set providing a standard for a player to make a judgment in selecting the most suitable golf club for the player.

In the golf club C with the head 2 mounted at the top of a shaft 1 and the grip 3 at the rear end of the shaft 1, the rotation moment at a position A, 170 mm from the rear and 3e of the grip 3 toward the top of the shaft 1 as the fulcrum, is measured, and the measured value is displayed at an arbitrary position in the golf club C. In the golf club set including plural golf clubs which are deferent in length, the rotation moment at the position A as the fulcrum is nearly unified among the golf clubs.
