Abstract: An external electrode includes a sintered metal layer disposed on at least an end surface and a conductive resin layer disposed on the sintered metal layer. The sintered metal layer includes a first portion, a second portion, and a third portion. The first portion is disposed at a central region of the end surface. The second portion is disposed at a part of a peripheral region of the end surface, and extends to an edge portion of the end surface from the first portion. The third portion is disposed at a remaining part of the peripheral region of the end surface. The thickness of the second portion is less than that of the first portion. The thickness of the third portion is less than that of the second portion. The first portion, the second portion, and the third portion are covered with the conductive resin layer.
