Abstract

See full text

In a three-terminal multilayer ceramic capacitor, each of first through fourth external electrodes includes a base electrode layer including a conductive metal and a glass component, an organic layer including an organosilicon compound covering the base electrode layer, and a plating layer on the organic layer. On a surface of the organic layer in a portion facing the plating layer, an atomic concentration ratio of Si to Cu is greater than or equal to about 1.5% and less than or equal to about 5.5%, or greater than or equal to about 0.8% and less than or equal to about 2.8%, and a surface roughness is greater than or equal to about 0.334 and less than or equal to about 0.371, or greater than or equal to about 0.352 and less than or equal to about 0.395.
