The present invention provides a golf ball, particularly a golf ball having excellent shot feel and spin performance without deteriorating flight distance and durability which are specific features of the solid golf ball. The solid golf ball of the present invention comprises a core (1) and a cover formed on the core, the cover having a two-layer cover structure of an inner cover layer (2) and an outer cover layer (3), wherein the core (1) is obtained from a rubber composition comprising 100 parts by weight of a base rubber and 18 to 28 parts by weight of a metal salt of an unsaturated carboxylic acid and the inner cover layer (2) has a specific gravity of 1.2 to 1.5, a thickness of 0.5 to 2.0 mm and a Shore D hardness within the range of more than that of the outer cover layer (3) and not more than 80 and, the outer cover layer (3) has a specific gravity of 0.5 to less than 1.2, a thickness of 1.0 to 2.5 mm and a Shore D hardness of 63 to 73.
