PROBLEM TO BE SOLVED : To obtain a reduction resistant dielectric composition low in rate of change of capacitance in wide temperature range having a long high temperature load life and a large dielectric constant at normal temperature. SOLUTION : This dielectric composition has composition ratio of Nb2O3 : 1.0-5.0 mole, ZnO : 1.0-5.0 mole, MgO : 0-3.0 mole, R2O3 : 0.5-5.0 mole (R is a rare earth element), BaSiO3 : 1.0-10 mole and MnO : 0.1-0.5 mole based on 100 mole of BaTiO3. A multilayer porcelain capacitor having a Ni internal electrode is produced by using the composition. |
