Zusammenfassung:With respect to a monolithic ceramic capacitor including external electrodes provided with a function as a resistance element, a favorable structure for the external electrode is provided, the structure being capable of preventing 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 can be realized. The structure of the external electrode (6 and 7) disposed on an outer surface of a capacitor main body (2) is allowed to include an electrically conductive layer (8) and a metal plating layer (9) disposed thereon, and the electrically conductive layer (8) is allowed to have a composition containing a compound oxide, e.g., an In-Sn compound oxide, which reacts with Ni or the Ni alloy, and a glass component.
