In a golf ball having a core or a sphere composed of a core enclosed by a cover layer and having also an outermost cover layer which covers a surface of the core or a surface of the sphere, the outermost cover layer is composed primarily of at least one thermoplastic resin or thermoset resin, which resin contains an inorganic composite material prepared by coating glass flakes with a metal or metal oxide. This arrangement provides a highly fashionable golf ball endowed with aesthetic characteristics that are novel and have a visual impact on the golfer.
