PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition which is free of variations in the composition after firing and makes homogeneous firing possible. SOLUTION: The dielectric ceramic composition contains an Si component at 35.0 to 65.0 wt.% in terms of SiO2, a Ba component at 20.0 to 50.0 wt.% in terms of BaCO3, a Mn component at 5.0 to 35.0 wt.% in term of MnCO3, an Al component at 3.0 to 10.0 wt.% in terms of Al2O3, a Cr component at 0.3 to 3.0 wt.% in terms of Cr2O3, and a Ca component at 0.3 to 3.0 wt.% in terms of CaCO3. |
