摘要：
A silver-coated material for a movable contact component includes an electrically conductive base member (1) that is comprised of copper or a copper alloy; an underlayer (2) that is comprised of nickel or a nickel alloy, and that has a thickness between 0.01 μm and 0.5 μm to coat on the electrically conductive base member; an intermediate layer (3) that is comprised of palladium, or a palladium alloy, or a silver tin alloy, and that has a thickness between 0.01 μm and 0.5 μm to coat on the underlayer; and an outermost surface layer (4) that is comprised of silver or a silver alloy, and that is formed on the intermediate layer.
