Abstract: A golf club 2 includes a head 4, a shaft 6, and a grip 8. A club inertia moment about a swing axis is defined as Isw. A club inertia moment about a grip end is defined as Ige. Ige is 2820 (kg·cm2) or greater and less than 2870 (kg·cm2). Isw/Ige is equal to or less than 2.42. A club weight is defined as Wc (kg), an axial direction distance from the grip end to a center of gravity of the club is defined as Lc (cm), and a club inertia moment about the center of gravity of the club is defined as Ic (kg·cm2).Isw is calculated by Equation (1) below. Ige is calculated by Equation (2) below. Isw=Wc×(Lc+60)2+Ic (1) Ige=Wc×(Lc)2+Ic (2)

Abstract: A head 2 includes a face surface 4, a back surface 6, and a sole surface 8. The back surface 6 includes a top side region Rt and a sole side region Rs. The sole side region Rs includes a sole side inclination surface Sb1 inclined to increase a face thickness toward a sole side, a plurality of back recessed parts Rb1 formed on the sole side inclination surface Sb1, and a wall WL1 formed between the back recessed parts Rb1 adjacent to each other. A low specific gravity member X1 having a specific gravity lower than the specific gravity of the face material is disposed on at least one of the back recessed parts Rb1. The head 2 has a loft angle of equal to or greater than 42°. The head 2 has a sweet spot height of equal to or greater than 19 mm.
