    摘要： A hollow golf ball comprising a hollow core and a cover layer that possesses good shot feel, an increased moment of inertia, and a high launch angle at the time of hitting. Immediately after impact, the hollow golf ball has a small spin amount. The specific hollow core reduces the rate of spin dumping between the ascending and descending of the ball, which results in increased flight distance. The hollow golf ball has a hollow core and a cover layer formed on the core, wherein the hollow core is composed of a hollow portion having a diameter of 5 to 30 mm and a core outer layer portion surrounding said hollow portion.

    摘要： An object of the present invention is to provide a golf ball having a great flight distance on driver shots. The present invention provides a golf ball having a spherical core and at least one cover layer covering the spherical core, wherein when JIS-C hardness, which is measured at nine points obtained by dividing a radius of the spherical core into equal parts having 12.5% intervals therebetween, is plotted against distance (%) from a core center, the spherical core is such that R2 of a linear approximation curve obtained from the least square method is 0.95 or higher, and a hardness difference between a core surface hardness and a core central hardness is 15 or higher in JIS-C hardness.
