| 简介 |
A multilayer ceramic capacitor includes a ceramic laminated body including dielectric ceramic layers and internal electrodes stacked with the dielectric ceramic layers disposed therebetween. The dielectric ceramic layers contain a perovskite compound containing Ba and Ti, Zr, and a rare earth element, and ratios of Zr and the rare earth element to 100 molar parts of Ti are about 0.4 to 2.0 molar parts and about 0.05 to 0.5 molar parts, respectively. The molar ratio of Zr to the rare earth element is about 3.3 to about 8.0, and Al-containing segregated substances are present in about 80% or more of defective portions where continuity of the internal electrodes is interrupted. Dielectric ceramic constituting the dielectric ceramic layers has an average grain diameter of about 230 nm to about 350 nm. |
