Abstract:
A multilayer ceramic capacitor includes a ceramic body including a stack of dielectric layers and internal electrodes and including main surfaces facing each other in a stacking direction, lateral surfaces facing each other in a width direction, and end surfaces facing each other in a length direction, and an external electrode electrically connected with the internal electrodes on the end surfaces. The external electrode includes an end surface covering portion covering each of the end surfaces, and a main surface covering portion covering portions of the main surfaces. The end surface and main surface covering portions each include a base electrode layer covering the ceramic body, and a plating layer covering the base electrode layer. The end surface covering portion further includes, between the base electrode layer and the plating layer, a sintered metal layer including a component different from that of the base electrode layer.
