    Abstract: An object of the present invention is to provide a golf ball having an excellent flight performance on driver shots. The present invention provides a golf ball comprising a spherical core and at least one cover covering the spherical core, wherein a hardness difference D1 (H75−H0) between a hardness H75 at a point located at a distance of 75% of a core radius from a center of the spherical core and a center hardness H0 of the spherical core is 15 or more and 35 or less in Shore C hardness, a hardness difference D2 (Hs−H75) between a surface hardness Hs of the spherical core and the hardness H75 at the point located at the distance of 75% of the core radius from the center of the spherical core is −1 or more and 3.5 or less in Shore C hardness, and a hardness difference D3 ((H0+H75)/2−H37.5) between a hardness of (the center hardness H0 of the spherical core+the hardness H75 at the point located at the distance of 75% of the core radius from the center of the spherical core)/2 and a hardness H37.5 at a point located at a distance of 37.5% of the core radius from the center of the spherical core is 0.5 or more and 6.5 or less in Shore C hardness.

    Abstract: A golf ball 2 includes a core 4 and a cover 6 positioned outside the core 4. The cover 6 has a thickness of 0.2 mm or greater and 1.0 mm or less. The cover 6 is formed by injecting a resin composition from an injection molding machine into a mold. The product (M*V*T) of: a melt fluidity M (g/10 min) of the resin composition, which is measured at 190° C.; an injection rate V (cm3/sec) of the injection molding machine; and an injection time T (sec) of the injection molding machine, is equal to or greater than 500 and equal to or less than 1000. Preferably, in the golf ball 2, the melt fluidity M of the resin composition is equal to or greater than 15 g/10 min and equal to or less than 100 g/10 min.
