  • Publication number: 20230197331
    Abstract: A method of manufacturing an electronic component capable of preventing entrance of a plating solution and a flux component at an interface to which an inner electrode of a ceramic element body is extended, and capable of forming an outer electrode of an arbitrary shape. A ceramic element body is made of a ceramic material containing a metal oxide, and part of an inner electrode is extended to extended surfaces of the ceramic element body. A base electrode is formed on each of the extended surfaces using a conductive paste to be connected to the inner electrode. Part of another surface of the ceramic element body adjacent to the extended surfaces is locally heated, and part of the metal oxide is reduced to form a reformed portion. A plating electrode is continuously formed over the base electrode and the reformed portion through a plating method to form outer electrodes.
