A high dielectric ceramic composition essentially consisting of 97.04 weight % to 97.80 weight % of BaTiO3 as a host material, 1.42 weight % to 1.92 weight % of Nb2O5, 0.04 weight % to 0.06 weight % of MnO2+L, 0.33 weight % to 0.45 weight % of CoO, 0.31 weight % to 0.41 weight % of CeO2 and 0.10 weight % to 0.12 weight % of ZnO. The composition exhibits TCC characteristic satisfying the characteristic of X7R of EIA standard, high dielectric constant of 3,200 to 3,800 and high insulation resistivity of 103 to 1014. With these characteristics, the composition is useful for making multi-layer ceramic capacitors, thereby contributing to a compactness of electronic/electric appliances.
