To make it possible to obtain a good trajectory, to increase carry at the time of a driver shot, to obtain an adequate spin quantity at the time of an approach shot and to obtain good controllability and an excellent ball hitting feel and durability.
The deformation quantity at the time of loading with 100 kg of the solid core of the multipiece solid golf ball consisting of the solid core and a cover of a two-layered structure consisting of an inside layer and outside layer covering the solid core is 3 to 7 mm. The inside layer cover described above has Shore D hardness of 25 to 58 and a thickness of 0.5 to 1.4 mm. The outside layer has Shore D hardness of 30 to 62 and a thickness of 1.2 to 2.3 mm. The ratio (thickness of the outside layer cover/thickness of the inside layer cover) of the thickness of the outside layer cover and the thickness of the inside layer cover is 1.1 to 4.6.
