The club length of a golf club is 43 inches or greater and 48 inches or less. A club inertia moment Ix about a swing axis is equal to or less than 6.90×103 (kg·cm2). A ratio (Ihs/Ix) is equal to or greater than 0.88, if a head inertia moment about the swing axis is defined as Ihs (kg·cm2). The inertia moment Ix (kg·cm2) is calculated by Equation (1) below, and the inertia moment Ihs (kg·cm2) is calculated by Equation (2) below: Ix=Wc×(Lc+60)2+Ic  (1) Ihs=Wh×(Lh+60)2+Ih  (2).
