DIELECTRIC CERAMIC COMPOSITION, LAMINATED CERAMIC CAPACITOR USING THE SAME AND METHOD FOR MANUFACTURING THAT CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition from which a laminated ceramic capacitor having excellent dielectric characteristics while satisfying X7R characteristics and further having little deviation in the dielectric characteristics and good reliability can be obtained, and to provide a method for manufacturing the laminated ceramic capacitor by using the above composition.;SOLUTION: The laminated ceramic capacitor is composed of dielectric layers (2), inner electrode layers (3) formed in the dielectric layers by alternately laminating with the dielectric layers, and external electrodes (4) electrically connected to the inner electrode layers (3) and the dielectric layers and formed on the both ends of the dielectric layers. The dielectric layers (2) contain 0.5 to 4 mol MgO, 0.01 to 0.5 mol MnO, 0.1 to 2 mol BaO, 0.1 to 2 mol CaO and 1 to 4 mol SiO2 to 100 mol BaCaxTiO3 (0.001≤x≤0.02) and further contain at least one component selected from the group consisting of Y2O3, Dy2O3, Ho2O3 and Er2O3 by 0.1 to 3 mol.;COPYRIGHT: (C)2002,JPO
