Title:
CERAMIC ELECTRONIC DEVICE AND METHOD OF MANUFACTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2002/082480
Kind Code:
A1
Abstract:
A ceramic electronic device comprises two or more electrodes (5, 6) arranged at a predetermined distance, between which a potential difference appears in operation. Gaps (9) coated with water-repellent film (10) and open to the outside are provided between electrodes (5, 6) to prevent water vapor from staying in the gaps. Electrical paths are thus prevented from forming, thereby preventing ion migration.
