Abstract
In a solid golf ball comprising a solid core and a cover, provided that a coefficient of restitution at a firing velocity of v m/s is designated by CORv, a ball structure prior to formation of the cover satisfies COR25-COR50≧0.100, and the ball satisfies COR50≧0.740 and COR25-COR50≧0.09. The golf ball's performance depends little on the head speed so that the flight performance of the ball when hit at a low head speed is improved while the flight performance when hit at a high head speed is little deteriorated.
