Patent ID: 7063813

Claim:
A method of producing a stacked ceramic body comprising the steps of: arranging a printed portion formed of an electrode paste consisting of copper or a copper compound as its main component on a green sheet formed of an oxide dielectric containing a lead oxide as its constituent element to form a print sheet; stacking a plurality of said print sheets to form an unsintered stacked body; conducting a degreasing treatment by heat-treating for removing organic components contained in said unsintered stacked body; and sintering said unsintered stacked body in a reducing atmosphere while controlling an oxygen partial pressure from room temperature to 400 to 600° C. to a range of 10 −10 to 10 −20 atm (1.013×10 −5 (=10 −4.994 ) to 1.013×10 −15 (=10 −14.99 )Pa) including an oxygen partial pressure at which copper and lead oxide can coexist, and a higher oxygen partial pressure than said oxygen partial pressure at which copper and lead oxide can coexist.
