Abstract
A multilayer ceramic capacitor has multiple laminated dielectric ceramic layers made of a dielectric ceramic, internal electrodes formed between the dielectric ceramic layers, and external electrodes electrically connected to the internal electrodes, wherein generation of cracks in the dielectric layer due to expansion of the internal electrode is suppressed by causing ceramic grains having a crystal axis ratio c/a higher than that of the ceramic grains constituting the dielectric layer to be present in non-contiguous parts of the internal electrodes between the dielectric ceramic layers, and by harnessing the stress-mitigating effect of domain switching involving these ceramic grains.
