Abstract
An object of the present disclosure is to provide a golf ball having excellent stability on an approach shot around the green while maintaining or improving a flight distance on a driver shot for a golfer with a slow head speed. The present disclosure provides a golf ball comprising a spherical core, and an outermost cover positioned outside the spherical core and having a plurality of dimples formed thereon, wherein when a hardness difference S (=Hs−Ho) between a surface hardness Hs of the spherical core and a center hardness Ho (Shore C hardness) of the spherical core, a material hardness C (Shore D hardness) of the outermost cover, and a total volume V (mm3) of the plurality of dimples below a surface of a virtual sphere satisfy V+S×C≤1200.
