Abstract
A multilayer ceramic capacitor includes: a multilayer structure in which dielectric layers and internal electrode layers are alternately stacked, the plurality of internal electrode layers being alternately exposed to a first edge face and a second edge face; and side margin regions that cover edge portions to which the plurality of internal electrode layers extend toward two side faces and have a structure in which a first ceramic layer and a second ceramic layer are alternately stacked in a stacking direction of the internal electrode layer and the dielectric layer, an amount of a second-phase of the first ceramic layer being larger than that of the second ceramic layer, a main component of the second-phase being SiOor a combination of SiOand BO, wherein a content ratio of the second-phase of the first ceramic layer is 15% or more and 45% or less.
