/Multilayer Ceramic Capacitor
Abstract

A multilayer ceramic capacitor includes a multilayer body, and an outer electrode. The multilayer body includes two major surfaces, two end surfaces, and two side surfaces. The outer electrode is provided on each end surface of the multilayer body. The multilayer body includes an inner layer portion, and an outer layer portion on opposite sides of the inner layer portion in a stacking direction. The inner layer portion includes an inner electrode, and an inner dielectric layer. The outer layer portion and the inner dielectric layer each include barium titanate as a major component, and Si as a minor component. A skewness of Si in the inner dielectric layer within a gap region is greater than the skewness of Si in the outer layer portion.
