Abstract
The dielectric material includes a pre-baked powder containing Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3, BaTiO.sub.3, and BaZrO.sub.3, and lead oxides alone or lead oxides and copper oxides in combination. Thus, the dielectric material is sintered at low temperatures of 800.degree.-1000.degree. C., and makes it possible to use inexpensive electrode materials such as copper, silver, and silver-palladium alloy for the electrode. The dielectric material also makes it possible to produce a ceramic condenser or a thin condenser having a stable capacitance irrespective of changes in temperature.
