ABSTRACT:
In a golf ball having a multiplicity of dimples of circular plane shape on its surface, the dimples include plural types of dimples having different diameters. The dimples of at least one type are formed to at least two different cross-sectional shapes. A three-dimensionally appropriate combination and arrangement of a multiplicity of dimples on the ball surface is effective for improving the aerodynamic behavior of the golf ball so that the ball exerts excellent flight performance.
