Abstract
A laminated ceramic capacitor which provides favorable properties and characteristics such as dielectric characteristics, insulation properties, temperature characteristics, and high temperature load characteristics and provides favorable thermal shock resistance, even when dielectric ceramic layers are reduced in layer thickness to increase the number of layers has dielectric ceramic layers containing, as their main constituent, a barium titanate based compound represented by the general formula ABOand internal electrodes containing Ni as their main constituent, which are stacked alternately. A crystalline oxide containing at least Mg and Li is present in at least either one of the internal electrodes and the dielectric ceramic layers. The crystalline oxide is preferably present mostly in contact with Ni in the internal electrodes.
