Abstract

An object of the present disclosure is to provide a golf ball that has a high spin rate but does not fly up in a high maximum flying height, thereby having a reduced number of shots into the OB area on a driver shot. The present disclosure provides a golf ball comprising a spherical core, an intermediate layer and an outermost cover, wherein a material hardness Hm (Shore D hardness) of the intermediate layer, a material hardness Hc (Shore D hardness) of the outermost cover, a thickness Tc (mm) of the outermost cover, and a total lower volume Vi (mm3) of a plurality of dimples satisfy Vi>365 and (Hc/Tc)×(Hm/Vi)≤7.5.
