摘要： An electronic component includes an electronic element and an interposer board. The electronic element includes a multilayer body and external electrodes at 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 surfaces and the board side surfaces. One of the board main surfaces is located in a vicinity of the electronic element and joined with one of the multilayer body main surfaces in a vicinity of the interposer board. The interposer board is an alumina board. The board end surfaces include a metal layer including a Pd-containing layer, and an electrolessly-plated layer on an outer periphery of the Pd-containing layer.

摘要： An outer electrode includes sintered layers each containing a sintered metal, an electrically insulating glass layer, and metal layers each containing at least one of Sn and Cu. Each sintered layer covers a respective end surface of a body and extends from the end surface to at least one main surface of the body. The glass layer is directly provided on the sintered layers located on the end surfaces of the body, extends in a direction perpendicular or substantially perpendicular to side surfaces of the body, and defines a portion of a surface of the outer electrode. Each metal layer covers a portion of one of the sintered layers other than a portion of the corresponding sintered layer that is covered with the glass layer, and defines another portion of the surface of the outer electrode.

摘要： 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.

摘要： 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.
