Abstract
A golf ball includes a core, a mid layer, and a cover. An amount of compressive deformation Cof the golf ball can be not less than 2.80 mm. The golf ball can satisfy the following mathematical formulas (1) and (2):1>(124.8−)/11.5  (1)2−1≥(−1/6*1+(68−2)/20+(5−)/100)*2  (2), where Cis an amount of compressive deformation (mm) of the core, Cis an amount of compressive deformation (mm) of a sphere including the core and the mid layer, Hd is Hs−Ho, Ho is a hardness (Shore C) of a center the core, Hs is a hardness (Shore C) of a surface of the core, His a hardness (Shore D) of the mid layer, and Tis a thickness (mm) of the mid layer.
