PURPOSE:To provide a dielectric ceramic having a high Q value in a microwave range, and having a stable crystal phase to be durable in usage in a field where high power is applied. CONSTITUTION:Dielectric ceramic composition is expressed by a general formula of BaO-x{(1-y)TiO2.yZrO2}, where x and y are in the ranges of 4.300<=x<=4.450 and 0<y<=0.10, MnO2 and Ta2O5 are added at rates of 0<MnO2<=0.5wt.% and 0<Ta2O5<=1.2wt.% respectively. |
