ABSTRACT:
A golf club with decreased air resistance in swinging to improve a head speed. A number of depressions 26 are formed on a back 4, a crown 6 and the side surfaces of a heel 7 and toe 8 of a head 1 of a wood club for example. Each depression 26 has a first side narrower than a second side thereof so that it is egg-shaped. The section of each depression 26 is formed smooth such that a slope at the first side is more gentle than that at the second side. Each depression 26 is desirably so oriented that its comparatively gentle slope is positioned at the face 3 side. Owing to these gentle slopes, the generation of a dead air region is suppressed at the inflow side of each depression 26, thus further decreasing an air resistance in swinging.
