An object of the present disclosure is to provide a golf ball having improved flight distance on driver shots and excellent spin performance on approach shots (particularly under the condition that there is grass between the golf ball and the club face) and on middle iron shots. The present disclosure provides a golf ball comprising a spherical core and a cover disposed outside the spherical core, wherein when a center hardness of the spherical core (Shore C hardness), hardnesses at 2.5 mm, 5 mm, 7.5 mm, 10 mm, 12.5 mm and 15 mm points from a center of the spherical core toward a surface of the spherical core (Shore C hardness), and a surface hardness of the spherical core (Shore C hardness) are represented by H<0>, H<2.5>, H<5>, H<7.5>, H<10>, H<12.5>, H<15> and H<s> respectively, the following relation is satisfied: H 2.5 − H 0 > H 12.5 − H 10 > H s − H 15 . <img class="EMIRef" id="c6f584fd-5a33-4cdc-a652-ae960662bcf6-ia01" />
