Abstract
A silver-plated product which has more excellent minute sliding abrasion resistance property than that of conventional silver-plated products, and a method for producing the same. The silver-plated product is produced by electroplating a base materialof copper or a copper alloy to form an underlying plating layerof nickel or a nickel alloy, a first silver-plating layer of silver (lower silver-plating layer), a zinc-plating layerof zinc serving as an intermediate plating layer, and a second silver-plating layer of silver (upper silver-plating layer)serving as a surface layer, in this order from the base material
