/Multilayer Ceramic Capacitor
Abstract

A multilayer ceramic capacitor includes a multilayer body, first and second outer electrodes, an inner layer portion and two outer layer portions on opposite sides of the inner layer portion. The inner layer portion includes a first inner electrode with one end exposed at a third surface, a second inner electrode with one end portion exposed at a fourth surface, and an inner dielectric layer including at least Ca, Sr, or Zr, and Li. In a region of the first or second outer electrode within an approximately 15 μm square area from an interface between the multilayer body and the first outer electrode or the second outer electrode, a Li content in the first outer electrode and/or the second outer electrode is less than a Li content in the inner dielectric layer.
