Multi-piece solid golf ball

A multi-piece solid golf ball comprising a core, at least one of an intermediate layer formed on the core and a cover covering the intermediate layer and having many dimples on the surface thereof, wherein

• a hardness difference in JIS-C hardness (HS−HC) between a surface hardness (HS) and a center hardness (HC) of the core is larger than 10,
• a hardness of the intermediate layer is lower than the surface hardness of the core, and the hardness in Shore D hardness of the intermediate layer is higher than 35,
• a ratio (TC/TI) of a thickness of the cover (TC) to that of the intermediate layer adjacent to the cover (TI) is larger than 0.7 and smaller than 1.2,
• a ratio (X/D) of the total of a periphery length of the dimple (X) to a diameter of the golf ball (D) is within the range of 90.0 to 118.0, and
• a ratio (VD/VG) of the total volume of the dimples (VD) to a volume of the phantom sphere (VG) assuming that the golf ball is a true sphere having no dimples on the surface thereof is within the range of 0.0108 to 0.0142.
