Abstract: 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.
