PURPOSE:To provide a dielectric porcelain composition capable of burning at low temperatures of <=1060 deg.C and capable of producing a porcelain showing a high Q value. CONSTITUTION:A dielectric porcelain composition compound mainly of (MgxA1-x)B2O6 and containing additives composed of one or more compounds selected from B2O3, SiO2 and LiO2 in an amount of 3-50 pts.wt based on 100 pts.wt main component. In the above-mentioned main component, (A) is one or more elements selected from Sr, Ca and Ba and (B) is one or more elements selected from Nb and Ta. (x) is a value within a range satisfying 0.03<=x<=1. |
