    摘要: To provide a non-reducing dielectric ceramic composition for multilayer ceramic capacitor, in which decrease of specific resistance and shortening of life time do not occur due to reduction of dielectric ceramic composition even when it is fired in neutral or reducing atmosphere and capacitance does not vary extensively due to temperature change, the non-reducing dielectric ceramic composition according to the present invention comprises 86.32 to 97.64 mols of BaTiO.sub.3, 0.01 to 10.00 mols of Y.sub.2 O.sub.3, 0.01 to 10.00 mols of MgO, and 0.001 to 0.200 mol of V.sub.2 O.sub.5. An additive containing 0.01 to 1.0 mol % of at least one or more of MnO, Cr.sub.2 O.sub.3, or Co.sub.2 O.sub.3, and further, an additive containing 0.5 to 10.0 mol % of {Ba.sub.A, Ca.sub.(1-A) }SiO.sub.3 (where 0.ltoreq.A.ltoreq.1) may be added.
