Claim Text:
1. A multilayer ceramic capacitor comprising: a ceramic laminated body including dielectric ceramic layers and internal electrodes stacked with the dielectric ceramic layers disposed therebetween; and external electrodes disposed on a predetermined area of the ceramic laminated body so as to be electrically connected to respective ones of the internal electrodes; wherein the dielectric ceramic layers include a perovskite compound including Ba and Ti, Zr, and a rare earth element; ratios of Zr and the rare earth element to 100 molar parts of Ti are within a range of: the internal electrodes include defective portions interrupting continuity of the internal electrodes; a proportion P1 determined by a formula P1=N1/N2×100 is about 80% or more, where N1 represents a total number of the defective portions including Al therein, and N2 represents a total number of the defective portions; and dielectric ceramic included in the dielectric ceramic layers has an average grain diameter within a range of about 230 nm to about 350 nm.
