Abstract
This invention provides a golf club with a club-head configured so as to decrease air resistance of the head by avoiding the air flows from retouching on the head surface. The club-head is provided with a ridge structure which contains a first ridge and a second ridge arranged at intervals in a downward direction of the air flows on at least the sole part of the head, wherein each of the ridges has the height of 0.2 mm to 3 mm and the breadth of 1 mm to 5 mm, the ridge structure being configured by plural ridges so as to displace the inclined angle of the ridges in a clockwise direction, resulting in generation of air vortex or whirls between the head surface and the surrounding air flows.
