Abstract:
A three-piece solid golf ball comprising a core, an intermediate layer formed on the core, and a cover covering the intermediate layer, whereinthe core has a JIS-C surface hardness of 65 to 83 wherein a distribution of JIS-C hardness, when determined at any two points between the center and the surface of the core has a difference of 5 or less and a deformation of 3.2 to 4.9 mm when applying an initial load of 10 kgf to a final load of 130 kgf on the core, the core is formed from a rubber composition comprising a base rubber, a co-crosslinking agent, an organic peroxide, and an organic sulfide compound, the organic sulfide compound being present in an amount of 0.05 to 5.0 parts by weight based on 100 parts by weight of the base rubber, the intermediate layer has a Shore D hardness of 63 to 70 and has a thickness of 1.0 to 2.5 mm, the cover has a Shore D hardness of 45 to 62, and a Shore D hardness difference between the intermediate layer and the cover is 3 to 20.
