ABSTRACT:
In an LW-reverse-type monolithic ceramic capacitor including external terminal electrodes each including a resistance component, internal electrodes include nickel or a nickel alloy, and the external terminal electrodes each include a first layer, a second layer provided on the first layer, and a third layer provided on the second layer. The first layer has a wrap-around portion extending from an end surface to principal surfaces and side surfaces of a capacitor main body, and contains a glass component and a compound oxide that reacts with Ni or the Ni alloy. The second layer covers the first layer such that the edge of the wrap-around portion of the first layer remains exposed, and contains a metal. The third layer covers the edge of the wrap-around portion of the first layer and the second layer, and is formed by plating.
