A golf club is provided to prevent reduction of a flying distance of a golf ball by slice since a golfer's hitting power acts in a fly direction of the golf ball without slipping aside in impact of the golf ball. A golf club includes: a shaft(10) gripped by a golfer; a head(20) impacting on a golf ball by being connected to the lower end of the shaft; and plural concave grooves(30) formed on an impact surface with the golf ball of the head. The impact surface of the head is formed in a flat surface, and the plural concave grooves of the impact surface are formed at regular intervals in a longitudinal direction and a transverse direction. |
