PROBLEM TO BE SOLVED : To provide a dielectric ceramic composition having excellent reduction resistance and excellent temperature stability of capacitance while keeping dielectric constant, and a laminated ceramic capacitor using the same.
SOLUTION : The dielectric ceramic composition contains barium titanate as a main component and 0.1-2.5 mol Mg expressed in terms of MgO, 1-5 mol in total of a rare earth metal A (at least one kind of Dy, Ho and Y) and a rare earth metal B (at least one kind of Yb, Er and Tm) per 100 mol barium titanate as assistant components and the ratio of magnesium to total of the rare earth A and the rare earth B is controlled to 0.1-2.0 and the ratio of the rare earth metal A to the rare earth metal B is controlled to 0.25-1.5. |
