Abstract:
External electrodes, electrically connected to exposed portions of internal electrodes, are arranged on end surfaces of a ceramic main body of a laminated ceramic capacitor. Alloy layers of a metal contained in internal electrodes, and a metal contained in external electrodes, are arranged at the boundaries between external electrodes, and the ceramic main body and internal electrodes. Plating layers are provided on surfaces of external electrodes. A ceramic electronic component having a reduced ESR is thus provided.

Abstract:
A ceramic electronic component includes a ceramic body, a plurality of internal electrodes provided in the ceramic body and including ends exposed on a surface of the ceramic body; a glass coating layer covering a portion of the surface of the ceramic body on which the internal electrodes are exposed; and an electrode terminal provided directly on the glass coating layer and including a plating film. The glass coating layer is made of a glass medium in which metal powder particles are dispersed. The internal electrodes project from the surface of the ceramic body into the glass coating layer without passing through the glass coating layer. The metal powder particles define conduction paths electrically connecting the internal electrodes with the electrode terminal.
