摘要： Golf ball 1 includes a core 2 and a cover 3. The core 2 has two layers including a center 4 and a mid layer 5. The mid layer 5 is formed by covering the center 4 with two half shells comprising a rubber composition, and by compression and heating of the center 4 and half shells in a mold. The rubber composition contains solid particles dispersed therein. The solid particles have a ratio “D/T”, i.e., a ratio of the particle size D to the thickness of the mid layer T, of equal to or greater than 0.3. Upon molding, the solid particles inhibit the center 4 to approach a cavity face. Accordingly, deviation of mass of the mid layer 5 can be suppressed. The solid particles have a ratio “W/T”, i.e., a ratio of the radial width W thereof to the thickness of the mid layer T, of from 0.3 to 1.0.
摘要翻译：高尔夫球1包括芯2和盖3。芯2具有包括中心4和中间层5的两层。中间层5通过用包含橡胶组合物的两个半壳覆盖中心4并且通过将模具中的中心4和半壳体压缩和加热来形成。橡胶组合物含有分散在其中的固体颗粒。固体颗粒具有比例“D / T”，即粒径D与中间层T的厚度之比等于或大于0.3。在成型时，固体颗粒抑制中心4接近空腔面。因此，可以抑制中间层5的质量的偏差。固体颗粒的比率“W / T”，即其径向宽度W与中间层T的厚度之比为0.3至1.0。
