Abstract
A golf ballincludes a core, a mid layer, and a cover. The coreincludes a centerand an envelope layer. The ratio of the volume Ve of the coreto the volume of a phantom sphere of the golf ballis equal to greater than 76%. The ratio (Co/Ce) of an amount of compressive deformation Co of the centerto an amount of compressive deformation Ce of the coreis greater than 2.0 but less than 3.0. The ratio (Vo/Ve) of the volume Vo of the centerto the volume Ve of the coreis equal to or greater than 0.01 but equal to or less than 0.13.
