ABSTRACT:
An object of the present invention is to provide a golf ball which is superior in durability to a golf ball having an ionomer resin cover which has conventionally been used. Another object of the present invention is to provide a golf ball using a non-petroleum based material. The golf ball of the present invention comprises a core and a cover covering the core, wherein at least either the core or the cover includes, as a resin component, a polyester resin containing a non-petroleum based material as a constitutional component.
