Abstract
An intercrystalline semiconductive ceramic capacitor having a dielectric ceramic body formed by sintering a dielectric ceramic having a composition essentially consisting of a major component comprised of 1 mole SrTiO.sub.3 and a minor component comprised of 0.01 to 0.04 mole TiO.sub.2, 0.001 to 0.010 mole Dy.sub.2 O.sub.3, 0.001 to 0.007 mole ZnO, 0.002 to 0.012 mole MnO.sub.2 and 0.01 to 0.07 mole Al.sub.2 O.sub.3 at a temperature of 1,400.degree. to 1,470.degree. C. in a reducing atmosphere, an intercrystalline insulation layer formed by coating an insulation paste over both surfaces of the dielectric ceramic body and heat treating the resultant body, and external electrodes formed on the both surface of the dielectric ceramic body, respectively.
