Abstract: A ceramic electronic component includes a ceramic body, a glass coating layer, and an electrode terminal. The ceramic body includes a plurality of internal electrodes whose ends are exposed on the surface of the ceramic body. The glass coating layer covers a portion of the ceramic body on which the internal electrodes are exposed. The electrode terminal is provided directly on the glass coating layer. The electrode terminal includes a plating film. The glass coating layer is made of a glass medium in which metal powder particles are dispersed. The metal powder particles define conduction paths that electrically connect the internal electrodes with the electrode terminal.

Abstract: In a multilayer ceramic capacitor in which an outer electrode is arranged on a ceramic element body to be electrically connected to an inner electrode, the outer electrode includes a metal electrode layer on the ceramic element body, and a conductive resin layer on the metal electrode layer. When a dielectric layer between a pair of the inner electrodes adjacent in a stacking direction among a plurality of the inner electrodes extending to one of a pair of end surfaces of the ceramic element body is an inter-electrode dielectric layer, a gap extends a direction connecting the adjacent inner electrodes sandwiching the inter-electrode dielectric layer at a position near or adjacent to at least the one of the end surfaces.

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 coating layer covering a surface portion of the ceramic body on which the internal electrodes are exposed, the coating layer being made of a glass or resin medium in which metal powder particles are dispersed; and an electrode terminal provided directly on the coating layer and including a plating film. The metal powder particles define conduction paths electrically connecting the internal electrodes with the electrode terminal and have an elongated shape in cross section along a thickness direction of the coating layer. The metal powder particles defining the conduction paths have a maximum diameter not smaller than the thickness of the coating layer.
