Abstract:
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.

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.
