Abstract

A method for forming a plurality of small concavities for forming dimples on the surface of the golf ball, on the hemispherical surface of the material of a master by electric discharge machining, is carried out in such a manner that the concavities are nonspherical in the direction perpendicular to the hemispherical surface and in a vertical section through each concavity.
