Abstract

An object of the present disclosure is to provide a golf ball having a small difference in the flight distance on a driver shot when hit at a high head speed and when hit at a low head speed. The present disclosure provides a golf ball comprising a spherical core, an intermediate layer and an outermost cover, wherein when a center hardness Ho (Shore C hardness) of the spherical core, a surface hardness Hs (Shore C hardness) of the spherical core, a hardness difference S=Hs-Ho, 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)×(S×Hm/Vi)≤130.
