Patent number: 8797711Abstract: 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. In a plating process, growth of the plating film constituting the external electrode is substantially stopped or delayed in the bump. As a result, a termination point of the growth of the plating film constituting the external electrode can be accurately controlled in the position of the bump.Type: GrantFiled: December 8, 2009Date of Patent: August 5, 2014Assignee: Murata Manufacturing Co., Ltd.Inventors: Seiichi Matsumoto, Toshiyuki Iwanaga, Makoto Ogawa, Akihiro Motoki
