Abstract
In a multi-piece golf ball comprising a core, an intermediate layer, and a cover, the ratio of A/B is set to be 1.10/1 or greater wherein A is a deflection under a load of 100 kg of the core and B is a deflection under a load of 100 kg of a sphere having the core enclosed with the intermediate layer, and the coefficient of restitution of the ball at a firing velocity of 25 m/s minus the coefficient of restitution of the ball at a firing velocity of 50 m/s is less than 0.100. The ball shows performance less dependent on a head speed, a distance exactly corresponding to a particular number of club used, and improved flight performance at a high head speed.
