PROBLEM TO BE SOLVED: To enhance reliability by constituting a dielectric ceramic layer of a laminated ceramic capacitor from a dielectric porcelain composite, that will not be reduced even if it is fired in a reducing environment. SOLUTION: A laminated ceramic capacitor 1 is prepared by forming outer electrodes 5 and plated layers 6 and 7 on both ends of a laminated ceramic body 3, which is laminated with plural dielectric ceramic layers 2a and 2b with inner electrodes 4 putting inside. The dielectric ceramic layers 2a and 2b have barium calcium titanate Ba1-xCaO}mTiO2, more than one kinds from among Y2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3 and Yb2O3, and MgO and MnO as main components, and contain either an oxide of Li2O-(Si,Ti)O2-MO based (MO is one kind from Al2O3 or ZiO2), or an oxide of SiO2-TiO2-XO based (XO is one kind from among BaO, CaO, a SrO, MgO, ZnO and MnO) as a sub constituent. The inner electrodes 4 are constituted of Ni or a Ni alloy. |
