Abstract: A ceramic electronic component includes a ceramic body, inner electrodes, a glass coating layer, and outer electrodes. The glass coating layer extends from an exposed portion of one of the inner electrodes at a first end surface to a first principal surface. The outer electrodes are each constituted by a plating film disposed directly above the glass coating layer. The glass coating layer includes a glass medium and metal powder particles that define conductive paths. The metal powder particles have an elongated or substantially elongated shape and are dispersed in the glass medium. The dimension of a portion of the glass coating layer located on the first principal surface in the length direction, is larger than that of a portion of the glass coating layer located on the first end surface in the thickness direction.
