    摘要： This invention provides a stacked ceramic body that prevents reaction between components of dielectric layers and components of electrode layers of an unsintered stacked body during sintering and in which both components do not easily form a liquid phase, and a production method of such a stacked ceramic body. A print portion 13 is formed on a green sheet 1, 12 containing lead by use of an electrode paste consisting of copper oxide as its main component. A desired number of print sheets 10 are stacked to give an unsintered stacked body 15. Degreasing is conducted in an atmosphere to degrease organic components. The print portion 13 is subjected to reducing treatment in a reducing atmosphere containing hydrogen and is converted to a print portion 13 containing copper as its main component. The unsintered stacked body 15 is sintered in a reducing atmosphere. Dielectric layers containing lead and electrode layers for applying a voltage to the dielectric layers are alternately stacked, and an oxidation portion containing copper is formed in the proximity of a surface of the electrode layer. A thickness of the oxidation portion in a stacking direction is 0.5 to 2 μm and a copper content in the oxidation portion is 1 to 30 wt %.
