PURPOSE:To provide a dielectric ceramic composition having a high dielectric constant, large no-load Q, and good stability of the temperature coefficient of resonance frequency. CONSTITUTION:A dielectric ceramic composition is made of barium, strontium, zinc, magnesium, niobium, antimony, and oxygen, and it is expressed by the composition formula 3(Ba1-xSrx)O.(Zn1-yMgy)O.(1-z)Nb2 O5.zSb2O5, where 0.4<x<0.8, 0<y<1, 0<z<0.20. |
