An object of the present invention is to improve the abrasion-resistance of a golf ball having a polyurethane cover. Another object of the present invention is to enhance the resilience and the shot feeling thereof. The present invention provides a golf ball having a cover, said cover comprising, as a base resin, a thermoplastic polyurethane containing a polycarbonate polyol as a constitutional component, wherein the polycarbonate polyol has, as a repeating constitutional unit, a repeating unit (A) shown in a following Formula (I), and a repeating unit (B) shown in a following Formula (II) and having a different structure from that of (A), and a molar ratio of (A)/(B) is from 30/70 to 70/30. In Formula (I), R<SUP>1 </SUP>is a bivalent residue obtained by removing two hydroxyl groups from a diol having 4 to 6 carbon atoms. In Formula (II), R<SUP>2 </SUP>is a bivalent residue obtained by removing two hydroxyl groups from a diol having 4 to 6 carbon atoms.
