MULTI-LAYER CERAMIC CAPACITOR AND METHOD FOR MANUFACTURING THE SAME

摘要

A multi-layer ceramic capacitor includes dielectric layers and internal electrode layers alternately laminated with the dielectric layers, wherein the proportion of dielectric grains constituting a dielectric layer that exists in one-layer-one-grain form is greater than 50%, and the average value of an electrode-grain aspect ratio, which represents the ratio of the maximum length, which is perpendicular to the thickness direction, to the maximum thickness of electrode grains constituting an internal electrode layer, is greater than 3.

1. A multi-layer ceramic capacitor comprising:
dielectric layers; and internal electrode layers alternately laminated with the dielectric layers, wherein more than 50% of dielectric grains constituting the dielectric layers exist in one-layer-one-grain form where a thickness of one dielectric layer and a size of the dielectric grains are approximately equal, and an average value of an electrode-grain aspect ratio of electrode grains constituting the internal electrode layers is larger than 3, said electrode-grain aspect ratio representing a ratio of a maximum grain length, which is perpendicular to the thickness direction, to a maximum grain thickness of the electrode grains.
