A golf ball composed of a core and one or more cover layer which encloses the core is characterized in that at least one cover layer is made of a thermoplastic polyurethane composition characterized by including at least 90 wt % of a thermoplastic polyurethane obtained by a polyurethane-forming reaction of an organic diisocyanate compound with a long-chain polyol and a chain extender, and in that the polyurethane composition cover layer is characterized that an inherent viscosity in a DMF solvent is larger than 1.5 dl/g and an inherent viscosity in a DMF solution containing 0.05 mol/L n-butylamine is larger than 0.5 dl/g. The golf ball has a high rebound, an excellent scuff resistance, is recyclable in a molding operation, and has excellent manufacturability.
