Original Abstract Submitted

a multilayer ceramic capacitor includes a multilayer body including ceramic layers and internal electrode layers, and external electrodes at both end surfaces of the multilayer body and each including a base electrode layer, a conductive resin layer on the base electrode layer, and a plated layer. the conductive resin layer includes an end-surface-side conductive resin layer portion on both end surfaces, and an adjacent conductive resin layer portion extending from an end portion of the end-surface-side conductive resin layer portion to be located on both main surfaces and both lateral surfaces. a content ratio of a resin component included in the adjacent conductive resin layer portion is greater than a content ratio of a resin component included in the end-surface-side conductive resin layer portion, and the content ratio of the resin component in the end-surface-side conductive resin layer portion is at least about 10% and no more than about 60%.
