PURPOSE:To manufacture such a non-reducing dielectric ceramic composition that can not reduced even if baked in a reducing atmosphere, may be high in dielectric constant and insulation resistance, and also may be stable in the rate of changes in the temperature of a dielectric. CONSTITUTION:A dielectric ceramic composition is manufactured by mutually compounding barium titanate (BaTiO3) powder whose alkali metal oxide content is less than 0.04wt.%, such an amount of an organic solvent soluble organic compound that may contain 0.60 to 0.72mol of Dy2O3, 1.20 to 1.44mol of CoO, 1.37 to 1.58mol of BaO, 0.60 to 0.72mol of NiO, 0.30 to 0.36mol of MnO and 1.80 to 2.16mol of MgO respectively against 100mol of the BaTiO3 powder, and 1.13 to 1.31wt.% of an organic solvent soluble organic compound forming an Li-Ba-Sr-Si group oxidic glass component respectively, then adding an organic solvent to the compounded material to be mixed together, and after removing the organic solvent from the resultant material heat-treating the material. |
