Abstract
A clubincludes a head, a shaft, and a grip. A club length Lis 43 inches or greater and 48 inches or less. A ratio (Wh/Wc) of a head weight Wh to a club weight Wc is equal to or greater than 0.66. An inertia moment Ix about a swing axis is 7.20×10(kg·cm) or greater and 7.50×10(kg·cm) or less. A static moment Mt (kg·cm) of the club is equal to or greater than 16.0 (kg·cm). The inertia moment Ix (kg·cm) is calculated by the following formula (1). Lc is an axial-directional distance between a grip end and a center of gravity of the club.×(+60)  (1)
