Abstract
The golf ball includes a core having an inner layer core and an outer layer core, a single-layered intermediate layer and cover, wherein the inner layer core is formed of a rubber composition, the intermediate layer and the cover are formed of a resin composition, and a relationship between an initial velocity of the inner layer core, an initial velocity of the entire core, an initial velocity of an intermediate layer-encased sphere, and an initial velocity of a ball satisfies the following conditions:(initial velocity of ball)<(initial velocity of intermediate layer-encased sphere)(initial velocity of intermediate layer-encased sphere)−(initial velocity of entire core)≤0.70 (m/s)(initial velocity of entire core)−(initial velocity of inner layer core)≥0.20 (m/s)
