Abstract
A multilayer ceramic capacitor that has alternately stacked dielectric layers containing, as their main constituent, a barium titanate based compound that has a perovskite-type crystal structure; and internal electrode layers with electrode defects. The internal electrode layers are 0.6 μm or less in thickness. The electrode defects have electrode defects containing an Al—Si based oxide mainly containing Al and Si. The number of the electrode defects containing the Al—Si based oxide is 30% or more in number ratio to the total number of electrode defects in the internal electrodes.
