Abstract
In a multi-piece solid golf ball comprising a solid core, an intermediate layer, and a cover, the intermediate layer has a gage G1 of 0.8-2 mm and a Shore D hardness of 50-65, the cover has a gage G2 of 0.5-1.3 mm and a Shore D hardness of 37-53, and the intermediate layer, gage G1 and the cover gage G2 satisfy [G1/(G1+G2)]×100≧45%. Upon full shots with a driver, the ball gains a reduced spin rate and an increased initial velocity, which lead to an increase in travel distance.
