A dielectric ceramic composition consists essentially of Al2O3 and additives composed of TiO2, MnO2 and at least one member selected from the group consisting of BaZrO3, CaTiO3 and SrTiO3, the contents of the additives per 100 parts by weight of Al2O3 being 0.5 to 10.0 parts by weight for TiO2, 0.5 to 6.0 parts by weight for MnO2 and not more than 20 parts by weight for at least one member selected from the group consisting for BaZrO3, CaTiO3 and SrTiO3. The dielectric ceramic composition may further contain at least one oxide selected from the group consisting of Co2O3, Fe2O3, NiO, Cr2O3 and CuO in an amount of not more than 5 parts by weight per 100 parts by weight of Al2O3.
