摘要： It is harder to realize structural defects when the thickness of an internal electrode is reduced in a laminated ceramic electronic component, such as a laminated ceramic capacitor, when the internal electrodes contain a base metal as their conductive constituent, and the dielectric ceramic layers are formed from a dielectric barium titanate ceramic, and as an accessory constituent, at least one alkali metal element selected from Li, K, and Na, each of the internal electrodes has a thickness of 0.5 μm or less, and the content of the alkali metal element in the dielectric ceramic is 0.2 parts by mol or more with respect to 100 parts by mol of the main constituent.

摘要： A monolithic ceramic capacitor having a large capacity and high reliability includes a ceramic sintered body including a plurality of stacked ceramic layers, and first and second inner electrodes and alternately disposed inside the ceramic sintered body to be opposed to each other in a stacking direction of the ceramic layers with one of the ceramic layers being interposed between the adjacent first and second inner electrodes. The ceramic sintered body includes a first portion in which the first and second inner electrodes are opposed to each other, and a second portion positioned outside the first portion. A ratio (Ic/Ia) of c-axis peak intensity (Ic) to a-axis peak intensity (Ia) measured with an XRD analysis of the one of the ceramic layers is about 2 or more.
