Disclosed is a solid golf ball (including a one piece solid golf ball and another type solid golf ball) which has excellent durability and a high impact resilience, as well as good feeling when struck. The solid golf ball of the present invention is characterized in that a hardness (H) of a rubber portion of the solid golf ball, when measured by a JIS-C hardness meter, decreases with distance from the surface to the center and satifies the following equation; n n When 0≦l≦5 416-6l≦5H≦440-6l n n n When 5<l≦r 77≦H≦82 n n wherein l is a distance in mm from the surface and r is the radius of the golf ball. |
