  • Ceramic electronic component and method for manufacturing the same
    Patent number: 6876537
    Abstract: A ceramic electronic component includes two or more electrodes 5 and 6 spaced at a predetermined distance from each other, between which a potential difference is produced in operation and a void 9 that penetrates to the outside is provided. In the void 9, a water repellent film 10 is formed. This prevents water vapor from being absorbed in the void 9 connecting the electrodes 5 and 6, and thereby preventing the formation of a conductive path and the occurrence of ion migration.
    Type: Grant
    Filed: August 13, 2003
    Date of Patent: April 5, 2005
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Norihisa Takahara, Emiko Igaki, Masakazu Tanahashi, Takafumi Moriyasu, Rui Nakao, Tomoyuki Washizaki, Yoshiaki Fukui
