ABSTRACT:
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.
