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.
