Stacked ceramic body is made by arranging a pressing part (13) made from copper or a copper compound as electrode paste on a green leaf (11, 12) formed from a dielectric oxide containing lead oxide as main component to form a pressing leaf (10), stacking pressing leaves, degreasing by heat treating and removing organic components contained in the non-sintered stacked body, and sintering. Production of a stacked ceramic body comprises: (a) arranging a pressing part (13) made from copper or a copper compound as electrode paste on a green leaf (11, 12) formed from a dielectric oxide containing lead oxide as the main component to form a pressing leaf (10); (b) stacking a number of pressing leaves to form a non-sintered stacked body; (c) degreasing by heat treating and removing organic components contained in the non-sintered stacked body; and (d) sintering the non-sintered stacked body whilst an oxygen partial pressure is adjusted from room temperature to 400-600 degrees C to an oxygen partial pressure at which copper and lead oxide are able to coexist or an oxygen partial pressure which is higher than the partial pressure at which copper and lead oxide are able to coexist. The non-sintered stacked body is sintered in a reducing atmosphere, the temperature is increased from room temperature, and an oxygen partial pressure is adjusted in the reducing atmosphere to 10-10 to 10-20 atm An Independent claim is also included for a stacked ceramic body produced by the above process. |
