摘要
Provided are: a plated member and a plated terminal for a connector, each comprising a silver-tin alloy layer that covers the surface of a basis material and a silver cover layer that covers the surface of the silver-tin alloy layer and suffering from little peeling of the silver-tin alloy layer; and processes by which said plated member and said plated terminal for a connector can be produced in a short time. A plated member which comprises a silver-tin alloy layer that covers the surface of a basis material and a silver cover layer that covers the surface of the silver-tin alloy layer and in which the silver cover layer is exposed on the outermost surface, wherein the silver-tin alloy layer exhibits, over the whole thickness region, an area fraction of voids of 30% or less in any plane parallel to the surface of the basis material. A process for producing said plated member, comprising: laminating tin plating layers and silver plating layers formed using a selenium-containing plating solution alternately on the surface of a basis material to form a laminated product in which the outermost layer is a silver plating layer; and then heating the laminated product.
