Abstract:
A multi-layer ceramic electronic device, comprisinga device body comprised of alternately arranged dielectric layers and internal electrode layers and external electrodes formed on an outer surface of the device body, each of the external electrodes having: an undercoat layer directly formed on the outer surface of the device body so as to be electrically connected with at least part of the internal electrode layers; an intermediate layer formed on an outer surface of the undercoat layer; an outer layer formed on an outer surface of the intermediate layer; the undercoat layer including a first conductive material mainly comprised of copper and a first glass ingredient; the intermediate layer including a second conductive material mainly comprised of a copper-palladium-based alloy; and the outer layer including a third conductive material mainly comprised of silver and further containing palladium and a second glass ingredient.
