Abstract:
A three-piece solid golf ball comprising a core composed of a center and an intermediate layer formed on the center, and a cover covering the core, whereinthe center has a diameter of 29 to 38 mm, a hardness difference in JIS-C hardness when determined at any point between a center point to surface of the center of not more than 7, and a specific gravity lower than that of the intermediate layer, the surface hardness in JIS-C hardness of the intermediate layer is higher than the hardness when determined at any point in the center and the difference between the surface hardness of the intermediate layer and the hardness when determined at any point in the center is within the range of 3 to 20, the cover has a Shore D hardness of less than 60 and wherein both the center and the intermediate layer are formed by vulcanizing a rubber composition comprising a base rubber, a co-crosslinking agent and an organic peroxide.
