ABSTRACT:
Disclosed are a CuO conductor paste which is effective for making a multilayered ceramic body, the conductor material of which is made of copper, and a method of manufacturing a multilayered ceramic body using the conductor paste. The conductor paste is made of CuO as the main component with an addition of at least one of PbO-based glass, or any of Bi.sub.2 O.sub.3 -based glass, CuO-based glass and CuAl.sub.2 O.sub.4 as the additive. The multilayered ceramic body is manufactured by a method comprising a forming process for making a multilayered body from the conductor paste and dielectric material, a binder removing process by heat treating the multilayered body, thus obtained, in air, a reduction process for reducing CuO to copper in a mixed gas atmosphere of hydrogen and nitrogen, and a sintering process for sintering the multilayered body thus reduced in a nitrogen gas atmosphere.
