An object of the present invention is to provide a golf ball traveling a greater distance by improving the properties of the spherical core. The present invention provides a golf ball comprising a spherical core, and at least one cover layer covering the spherical core, wherein the spherical core is formed from a rubber composition containing a base rubber, a co-crosslinking agent, a crosslinking initiator, a filler and a polynuclear aromatic organic sulfur compound or a derivative thereof, and the spherical core has a specific hardness distribution without decreasing hardness from a central point toward a surface of the spherical core in JIS-C hardness.
本发明的目的是通过改善球心的特性,提供一个能够飞行更远的高尔夫球。本发明提供了一种高尔夫球,包括一个球心和至少一层覆盖在球心上的外覆层,其中球心由一种橡胶组合物形成,该组合物包含基础橡胶、共交联剂、交联引发剂、填料和多核芳香有机硫化合物或其衍生物,并且球心在JIS-C硬度上具有特定的硬度分布,从球心中心向表面不降低硬度。
