In a multi-piece solid golf ball comprising a solid core, an intermediate layer, and a cover, the intermediate layer has a gage G.sub.1 of 0.8 2 mm and a Shore D hardness of 50 65, the cover has a gage G.sub.2 of 0.5 1.3 mm and a Shore D hardness of 37 53, and the intermediate layer gage G.sub.1 and the cover gage G.sub.2 satisfy [G.sub.1/(G.sub.1+G.sub.2)].times.100.gtoreq.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.
