ABSTRACT:
Internal electrodes formed in the interior of a ceramic laminate of a monolithic ceramic capacitor comprise metal conductor parts and semiconductor parts. The semiconductor parts are exposed at both end surfaces of the ceramic laminate to be electrically connected with external electrodes. The external electrodes comprise baked layers of silver formed on the end surfaces of the ceramic laminate and metal plated films formed thereon. In formation of the metal plated films, a plating solution which may reach the end surfaces of the ceramic laminate through the baked layers is blocked by the semiconductor parts and prevented from infiltration into the metal conductor parts of the internal electrodes.
