MULTILAYER CERAMIC ELECTRONIC COMPONENT
Abstract:
A multilayer ceramic capacitor includes a ceramic element body including internal electrodes therein. External electrodes are provided on end surfaces of the ceramic element body and electrically connected to exposed portions of respective ones of the internal electrodes. Each of the external electrodes includes a sintered metal layer, a conductive resin layer, and a plating layer. In a cross section including a first interface between the sintered metal layer and the conductive resin layer, the sintered metal layer includes a plurality of recesses each including an inlet extending along the first interface and an inner portion extending from the first interface into the sintered metal layer, each of the recesses having a shape in which a dimension of the inner portion is larger than a dimension of the inlet measured along the first interface, and in a cross section including a second interface between the conductive resin layer and the plating layer, a number of the metal particles exposed from the conductive resin layer in a portion of the second interface with a length of about 1 mm is 50 to 250.
