Abstract: In an embodiment, a multilayer ceramic capacitor 10 has a capacitor body comprising a capacitive part 11a constituted by multiple internal electrode layers 11al that are stacked with dielectric layers 11a2 in between, as well as dielectric cover parts 11b that respectively cover both sides of the capacitive part 11a in the stacking direction. Also, the dielectric layers 11a2 of the capacitive part 11a, and the dielectric cover parts 11b, contain elemental manganese, and the elemental manganese is distributed in such a way that its quantity gradually decreases in the depth direction from the exterior faces of the dielectric cover parts 11b toward the center of the dielectric layers 11a2 of the capacitive part 11a.
