MULTILAYER CERAMIC CAPACITOR, DIELECTRIC CERAMIC, MULTILAYER CERAMIC ELECTRONIC COMPONENT, AND METHOD FOR MANUFACTURING MULTILAYER CERAMIC CAPACITOR

摘要

A dielectric ceramic that can be sintered at a sufficiently low temperature and has a desired specific resistance at a high temperature, and a multilayer ceramic electronic component (a multilayer ceramic capacitor and the like) using the dielectric ceramic are provided. The multilayer ceramic capacitor includes a multilayer body having a plurality of laminated dielectric ceramic layers, and a plurality of internal electrodes at interfaces between the dielectric ceramic layers; and external electrodes 8 and 9 on outer surfaces of the multilayer body. The composition of the multilayer body includes a perovskite-type compound containing Ba and Ti (where a part of Ba may be substituted by Ca, and a part of Ti may be substituted by Zr) as a primary ingredient, and further includes M (where M is at least one of Cu, Zn, Li, K, and Na) and Bi. The total content of M and Bi is equal to or greater than 3 molar parts when the total content of Ti and Zr is 100 molar parts. The crystal particle size of the dielectric ceramic is 30 nm or more and 150 nm or less.
