    摘要： An object of the present invention is to provide a golf ball having an excellent spin performance on approach shots under a wet condition. The present invention provides a golf ball comprising a spherical core and a cover covering the spherical core, wherein the cover is formed from a cover composition containing (A) a polyurethane and (B) a polyrotaxane as a resin component, and wherein (B) the polyrotaxane has a cyclodextrin, a linear molecule piercing through the cyclic structure of the cyclodextrin, and blocking groups located at both terminals of the linear molecule to prevent disassociation of the cyclodextrin, and at least a part of hydroxyl groups of the cyclodextrin is modified with a caprolactone chain via —O—C3H6—O— group.
