Abstract
A golf ball includes a solid core and a cover of at least one layer; wherein each of a specific gravity of the solid core and a specific gravity of the cover is nearly equal to a value (S) of a relation expression given by S=W/[(&pgr;/6)×D ], where W is a weight of the golf ball and D is a diameter of the golf ball. The golf ball can enhance the durability to increase the carry of the ball with less variations in carry of the ball.
