    Abstract: A ceramic electronic component includes a ceramic base body and first and second outer electrodes. The ceramic base body includes first and second primary surfaces, first and second side surfaces, and first and second end surfaces. The first and second outer electrodes are arranged on the ceramic base body so that front end portions of the outer electrodes face each other. The first and the second outer electrodes include outermost layers each containing Cu. Outermost layers of the facing front end portions of the first and the second outer electrodes are more oxidized than outermost layers of the other portions of the first and the second outer electrodes.

    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: An electronic component includes an electronic element and an interposer board. The electronic element includes a multilayer body and external electrodes each at a respective one of multilayer body end surfaces of the multilayer body and connected to internal electrode layers. The interposer board includes board end surfaces, board side surfaces orthogonal to the board end surfaces, and board main surfaces orthogonal to the board end surface and the board side surface. One of the board main surfaces is located in a vicinity of the electronic element and joined with one of the pair of multilayer body main surfaces in a vicinity of the interposer board. The interposer board is an alumina board. The pair of board end surfaces include a metal layer including a Cu-containing layer and a Cu plated layer on an outer periphery of the Cu-containing layer.
