Abstract:
A multi-piece solid golf ball comprising a solid core, an intermediate layer around the core, and a cover around the intermediate layer, whereinsaid solid core has a diameter of 32.0 to 38.7 mm and a maximum hardness at a position spaced 4 to 9 mm radially inward from its surface and a hardness at its center, the difference between the maximum hardness and the center hardness being at least 3 JIS-C hardness units, said intermediate layer is harder than said cover, and said cover has a gage of up to 2.0 mm, wherein said solid core has a compression of 2.6 to 4.5 mm and a spherical body obtained by enclosing the solid core with the intermediate layer has a compression of 2.5 to 4.0 mm, and said ball composed of said solid core, said intermediate layer and said cover has a compression of 2.2 to 3.3 mm, wherein said compression refers to the amount of deflection incurred by each of the solid core, the spherical body and the ball when subjected to a load of 1,275N from an initial load of 98N.
