Abstract:
A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers alternately laminated therein, and external electrode layers respectively provided on both end surfaces of the multilayer body in a length direction intersecting a lamination direction, and each connected to the internal electrode layers, the external electrode layers each further including a base electrode layer including a first region, a second region, and a third region divided therein, in order from the multilayer body. The first region includes a metal included in the internal electrode layers in a higher amount than the second region and the third region, the second region includes glass in a higher amount than the first region and the third region, and the third region includes copper in a higher amount than the first region and the second region.
