Abstract
To provide a multilayer ceramic capacitor that is enhanced in moisture resistance of a dielectric material of a portion surrounding the outside of a plurality of laminated internal electrode layers to ensure the moisture resistance of the multilayer ceramic capacitor.SOLUTION: A plurality of dielectric layers 140 includes outer dielectric layers located between an internal electrode layer 150 located to be closest to a first main surface 111 side in a thickness direction T and the first main surface 111, and between an internal electrode layer 150 located to be closest to a second main surface 112 side in the thickness direction T and the second main surface 112, and inner layer dielectric layers located between the internal electrode layers 150 adjacent to each other in the thickness direction T. In an element body 110, side margin portions S1, S2 located between a first side surface 113 and the plurality of internal electrode layers 150 and between a second side surface 114 and the plurality of internal electrode layers 150 in a width direction W have a higher Mn content than the inner dielectric layers.SELECTED DRAWING: Figure 13
