Patent ID: 7841954

Claim:
A multi-piece solid golf ball which consists essentially of a core consisting of a center and an intermediate layer formed on the center, and a cover covering the core, wherein the center has a diameter of not less than 39.2 mm to less than 41.3 mm, a surface hardness in Shore D hardness higher than a central point in Shore D hardness by 15 to 40, the intermediate layer is formed from thermoplastic resin as a main component and has a thickness of not less than 0.3 to less than 1.0 mm, the cover is formed from a polyurethane-based thermoplastic elastomer formed by using cycloaliphatic diisocyanate as a main component, and has a thickness of not less than 0.3 to less than 1.0 mm and a hardness in Shore D hardness of not less than 35 to less than 55, a hardness in Shore D hardness of the intermediate layer is higher than the surface hardness of the center and the hardness of the cover, and when a deformation amount of the center and that of the core when applying from an initial load of 98 N to a final load of 1275 N are represented by “A (mm)” and “B (mm)” respectively, the value of deformation amount difference (A−B) is within the range of not less than 0.15 mm to less than 0.35 mm.
