Abstract:
An external electrode structure for a monolithic ceramic capacitor provided with a function as a resistance element is capable of preventing a reduction of the external electrode due to baking in a reducing atmosphere, so that Ni or a Ni alloy can be used in an internal electrode and a good electrical connection between the internal electrode and the external electrode is achieved. The external electrodes disposed on an outer surface of a capacitor main body include an electrically conductive layer and a metal plating layer disposed thereon, and the electrically conductive layer includes a compound oxide, e.g., an In—Sn compound oxide, which reacts with Ni or the Ni alloy, and a glass component.
