Abstract
A multilayer ceramic capacitor includes an element body portion including internal electrode layers, and first and second external electrodes. In the internal electrode layers, a width of an opposing portion is larger than a width of a lead-out portion, each of the first and second external electrodes includes a Cu layer on the element body portion including first and second layer portions. The first layer portion has a higher Cu content than the second layer portion, the second layer portion has a higher glass content than the first layer portion. The Cu in the first layer portion is continuous to connect lead-out portions adjacent to each other. In a cross section of the second layer portion extending through a central portion in the width direction and parallel to the thickness and length directions, the glass occupies about 25% or more of an area of the second layer portion.
