Abstract
A golf ball includes a core, an intermediate layer, and a cover, in which an initial velocity is not more than 76.0 m/s, a deflection when the ball is compressed under a specific load is at least 2.8 mm, and letting a value of (initial velocity of core×weight of core) be Ciw, a value of [(initial velocity of intermediate layer-encased sphere−initial velocity of core)×(weight of intermediate layer-encased sphere−weight of core)] be Miw, and a value of [(initial velocity of ball−initial velocity of intermediate layer-encased sphere)×(weight of ball−weight of intermediate layer-encased sphere)] be CViw, the condition is of Ciw+Miw+CViw≤2,550 is satisfied, thereby to be capable of making a distance for reducing a distance on shots with a driver and an iron by average hitters smaller.
