Abstract
A golf ballincludes a coreand a coverpositioned outside the core. The coveris molded in a mold having support pins by injection molding. A ratio (K/S) of a surface hardness K of the coreto an amount of compressive deformation S of the coresatisfies the following mathematical formula.13.0≤≤24.0The coverhas a hardness H of not greater than 62. A product (α*V) of a latitude α of each support pin and a volume V of the coveris not less than 300.
