An object of the present invention is to improve abrasion-resistance and spin performance of a golf ball having a polyurethane cover. The golf ball of the present invention is a golf ball having a core and a cover covering the core. The cover contains a layered silicate and a polyurethane resin having a secondary or a tertiary amine structure in a molecular chain thereof. In the present invention, the polyurethane resin used as a resin component constituting the cover has a secondary or tertiary amine structure in a molecular chain. Thus, it has a strong interaction with the layered silicate, and a reinforcing effect of the filler becomes even higher. As a result, abrasion-resistance and spin performance of the resultant cover are improved.
