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 has numerous dimples 4 on its surface. The dimple 4 comprises an inclined face 6, a circular flat face 7, an annular groove 8 and a round flat face 9. Surface area s1 is calculated by summing up the surface area of the inclined face 6, the surface area of the circular flat face 7, the surface area of the annular groove 8 and the surface area of the round flat face 9. The ratio (S1/S2) between a summation S1 of surface areas s1 of all the dimples, and a summation S2 of the areas s2 of the regions cut away by the dimples on the phantom spherical face is equal to or greater than 1.02. Total value (Cb+Cc) of the amount of compressive deformation Cb of the golf ball 1 and the amount of compressive deformation Cc of the core is equal to or greater than 7.0 mm.

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.
