Original Abstract Submitted

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.
