ABSTRACT:
A dielectric ceramic composition of matter characterized in that the composition of matter contains 0.003 to 0.3% by weight manganese in addition to the main composition of matter represented by the composition formula xBaO.multidot.yNd.sub.2 O.sub.3 .multidot.zTiO.sub.2 .multidot.wBi.sub.2 O.sub.3 wherein 0.110.ltoreq.x.ltoreq.0.170, 0.120.ltoreq.y.ltoreq.0.185, 0.630.ltoreq.z.ltoreq. 0.710, 0.020.ltoreq.w.ltoreq.0.090, and x+y+z+w=1. This composition of matter is high in dielectric constant, low in the temperature dependency of resonance frequency in a resonator, and high in Q-value.
