Abstract

The dielectric ceramic composition contains 40-54 wt.% SrTiO3, 18-25 wt.% PbTiO3, 15-30 wt.% Bi2O3‧nTiO2 (n represents compound ratio) and 8-12 wt.% CaTiO3 as essential ingredients and 0.1-0.5 wt.% CuO, 0.05-0.5 wt.% Nb2O5 and 0.05-0.5 wt.% MnO as accessory ingredients based on 100 wt.% essential ingredients. According to the invention, the dielectric ceramic composition exhibits low loss in a high frequency zone, has both relative permittivity and the rate of change of dielectric temperature characteristics in a high level.
