The laminaled magnetic condenser using nickel or nickel alloy as an internal electrode is produced by (a) mixing barium carbonate, titania, strontium carbonate, nickel oxide and zirconia, (b) drying and calcinting at 1,050-1,200 deg.C for 2hs. (c) preparing the slurry with the calcined dielectric ceramics and the organic binder, PVB, (d) manufacturing the dielectric green sheet of the thickness 20-50 micrometer by doctor blade method, (e) coating paste for nickel electrode on the dielectric sheet, (f) laminating and sintering at 1,300-1,400 deg.C in the reduction atmosphere of low oxygen partial pressure, 10-8-10-12 MPa. The reduction resisting dielectric composition comprises Ba1-xSrxTi1-y-xNiyZr2O3-y, where x, y, z are in the ranges from 1, 0.005, 0 to 0.2, 0.1, 0.2, respectively.
