PURPOSE:To provide a ceramic capacitor or a thick film capacitor using a dielectric porcelain composite having a baking temperature 800 to 1000 deg.C while the composite can be baked in the atmosphere, neutral atmosphere or reduced atmosphere in a short time and having a low dielectric loss at high frequency. CONSTITUTION:A dielectric porcelain composite is provided with the constitution, in which PbO 1.0 to 25.0 molar % and MgO 10.0 to 200.0 molar % or MnO2 1.0 to 15.0 molar % are added to tentative baked powder of a main component dielectric porcelain composite consisting of Pb(Mg1/3Nb2/3)O3, PbTiO3, Pb(Ni1/2W1/2)O3. Further, the dielectric porcelain composite is also provided with the constitution, in which PbO 1.0 to 25.0 molar % and MgO 10.0 to 250.0 molar % are added to tentative baked powder of the main component dielectric porcelain composite, in which MnO2 is added to a three-component lead solid solution of PbTiO3, Pb(Mg1/3 Nb2/3)O3, PbZrO3. |
