摘要： The present invention provides a golf ball comprising a core and a cover covering the core, wherein the cover layer comprises a 3-dimensional shaped metal oxide having at least three needle-shaped parts. Blending the 3-dimensional shaped metal oxide into the cover layer enhances the rigidity of the resultant cover for the hardness thereof. In the case that the cover layer has the slab hardness of 57D or more in shore D hardness, this property can be used to enhance the resilience without lowering the shot feeling. On the other hand, in the case that the cover layer has the slab hardness less than 57D in shore D hardness, this property can be used to enhance the resilience without lowering the spin rate.

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.
