Abstract
In a solid golf ball of multilayer structure comprising a core, an enclosing layer, and a cover, the core and the enclosing layer have volumes V and V which satisfy 0.05%≦V /V ×100%≦60%, and the core has a rebound of A (cm) and the core enclosed with the enclosing layer has a rebound of B (cm) both when dropped from a height of 120 cm, which satisfy A<B. The ball travels an increased carry at both high and low club-head speeds and ensures greater carry for low head speed players.
