Abstract
A golf ball includes a core, a mid layer, and a cover. A ratio Rcalculated by mathematical formula (1): R=(Df−Df)/(Df−Df) is not less than 5.00. A ratio Rcalculated by mathematical formula (2): R=(T*H)/His not less than 2.00. A ratio Rcalculated by mathematical formula (3): R=D/Tis less than 50. In mathematical formulas (1) to (3), Dfrepresents an amount of compressive deformation of the core, Dfrepresents an amount of compressive deformation of a sphere including the core and the mid layer, Dfrepresents an amount of compressive deformation of the golf ball, Trepresents a thickness of the mid layer, Hrepresents a hardness of the mid layer, Hrepresents a hardness of the cover, Drepresents a diameter of the core, and Trepresents a thickness of the cover.
