A solid golf ball with a polyurethane cover is provided which is satisfactory in the moldability of the cover and in ball characteristics such as a shot feeling and a flight distance. The solid golf ball of the invention includes a solid center, an intermediate layer, and a polyurethane cover. A material having a flexural modulus of from 150 to 420 MPa is used for the intermediate layer in order for the golf ball to offer satisfactory shot feeling and flight distance. By the use of a vulcanizate of a rubber composition containing a diphenyl disulfide for the solid center, the golf ball can exhibit an increased flight distance. In order to enhance the moldability of the cover a urethane prepolymer having a residual isocyanate monomer content of not more than 0.5% by mass is used. |
