Claim:
A multi-piece solid golf ball comprising a solid core of at least one layer, an intermediate layer enclosing the solid core, and a cover enclosing the intermediate layer, wherein said intermediate layer has a gage G 1 of 0.8 to 1.5 mm and a Shore D hardness of 50 to 65, said cover has a gage G 2 of 0.5 to 1.3 mm and a Shore D hardness of 37 to 50 and is formed of an urethane resin, and the gage G 1 of said intermediate layer and the gage G 2 of said cover satisfy 67.9%≧[G 1 /(G 1 +G 2 )]×100≧51.7% and said hardness of said intermediate layer is higher than said hardness of said cover, and wherein said solid core, a spherical body obtained by enclosing the core with the intermediate layer and a spherical body obtained by enclosing the intermediate layer with the cover undergo a deflection of 3 to 4.5 mm, 2.8 to 6.0 mm and 2.5 to 4.0 mm under an applied load of 100 kg, respectively.
