Abstract
In a multi-piece solid golf ball having a core formed of a center core encased by an envelope layer, a cover having a plurality of dimples on its surface, and one or more intermediate layer disposed between the core and the cover, the center core and the envelope layer are each made of an elastic material, the radius r (mm) of the center core satisfies the condition 5≦r≦15, and the core has a cross-sectional hardness profile that satisfies specific conditions. This golf ball has an increased distance and a soft feel at impact, and also is able to prevent a decline in the durability to cracking.
