In a multi-piece solid golf ball comprising a rubbery elastic solid core and a resin cover including at least an inner layer, an intermediate layer and an outer layer, the solid core undergoes a deflection of 1.6-6.0 mm under an applied load of 294 N (30 kgf), the cover inner layer has a Shore D hardness of 55-70, the cover intermediate layer has a Shore D hardness of 8-50 and a gage of 0.1-1.2 mm, and the cover outer layer has a Shore D hardness of 40-55. The ball prevents any undesired increase of spin upon driver shots without detracting from rebound, has good flight performance, and receives enough spin to facilitate control on short iron shots.
A multi-piece solid golf ball comprising a rubbery elastic solid core and a resin cover enclosing the solid core, said cover comprising at least three layers including an inner layer disposed adjacent to the solid core, an outer layer disposed radially outside the inner layer and provided on its outer surface with a multiplicity of dimples, and an intermediate layer between the inner layer and the outer layer, wherein
