A multi-piece solid golf ball core with inner layer and outer layer, and at least one layer of cover on the core, with an inner layer core diameter of 24 to 40 mm and a center hardness in JIS-C hardness of 40 to 60; a surface hardness in JIS-C hardness of the inner layer core higher than the center hardness by 20 to 40; the outer layer core thickness of 2.0 to 7.0 mm and a surface hardness in JIS-C hardness of 75 to 90; the outermost layer of the cover 1.0 to 2.0 mm thick and a Shore D of 40 to 63; and the golfball satisfies formula: 0<={T(C-B)-(60-A)}<=10; where:A, B represent inner layer core's center hardness, surface hardness, respectively, JIS-C;C represents surface hardness (JIS-C) of outer layer core;T represents thickness of outer layer core. |
