Publication number: 20100157507Abstract: A region where a plating film constituting an external electrode is formed can be accurately controlled in an electronic component in which the external electrode is formed by directly plating a particular region in a surface of a component body. In a component body, a bump is provided in a position in which a region where an external electrode should be formed is partitioned.
