The present invention provides a three-piece solid golf ball having long flight distance, by accomplishing high launch angle and low spin amount immediately after hitting, while maintaining soft and good shot feel when hitting at low head speed. The present invention relates to a three-piece solid golf ball comprising a center, an intermediate layer formed on the center, and an outer layer covering the intermediate layer, wherein the center has a central point hardness in JIS-C hardness of 55 to 75 and a surface hardness in JIS-C hardness of 65 to 85, the surface hardness is higher than the central point hardness by 10 to 20, a JIS-C hardness of the intermediate layer is higher than the surface hardness of the center by 10 to 20, and a JIS-C hardness of the outer layer is higher than the hardness of the intermediate layer by 5 to 15.
