Abstract
The invention provides a multi-piece solid golf ball having improved flight performance, controllability and good shot feel at the time of hitting. The multi-piece solid gold ball has a core having at least one layer, an intermediate layer formed on the core, and a cover covering the intermediate layer. When thickness of the intermediate layer is represented as X (mm) and JIS-C hardness of the intermediate layer is represented as Y, then X is 0.3 to 1.5 mm, X and Y have a correlation represented 10X+55≦Y≦10X+75, and the JIS-C hardness of the cover is 70 to 93.
