Abstract
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.

A monolithic ceramic capacitor comprising:
- a ceramic sintered body including a plurality of stacked ceramic layers;
- and
- first and second inner electrodes 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;
- wherein
- 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;
- and
- in the first portion, the ceramic layers are oriented in the stacking direction, and a ratio (Ic/Ia) of c-axis peak intensity (Ic) to a-axis peak intensity (Ia) measured with an XRD analysis of at least the one of the ceramic layers is about 2 or more.
