1. A golf club comprising:
- a shaft;
a head attached to a tip part of the shaft; and
a grip attached to a rear end part of the shaft,wherein;
the head includes a sole surface and a face surface having a face line;
the sole surface includes a ridgeline extending from a toe side toward a heel side, a leading surface positioned on a face side of the ridgeline and inclined upward toward the face side, and a trailing surface positioned on a back side of the ridgeline and inclined upward toward the back side; and
if an inclination angle of the trailing surface is defined as θ
2;
the inclination angle θ
2 at a central position of the face line is defined as θ
2c;
the inclination angle θ
2 at a toe reference position is defined as θ
2t; and
the inclination angle θ
2 at a heel reference position is defined as θ
2h, the golf club satisfies at least one of the following (a) and (b);
(a) the inclination angle θ
2t is greater than the inclination angle θ
2c;
(b) the inclination angle θ
2h is greater than the inclination angle θ
2c.

Abstract
A golf club 4 includes a head hd and a sole surface 12. The sole surface 12 includes a ridgeline RL extending from a toe side toward a heel side, a leading surface Si positioned on a face side of the ridgeline RL and inclined upward toward the face side, and a trailing surface S2 positioned on a back side of the ridgeline RL and inclined upward toward the back side. Inclination angles at respective positions of the trailing surface S2 are defined as θ2c at a central position, θ2t at a toe reference position, and θ2h at a heel reference position. Then, the head hd satisfies at least one of the following (a) and (b):
- (a) The inclination angle θ2t is greater than the inclination angle θ2c
- (b) The inclination angle θ2h is greater than the inclination angle θ2c.
