Abstract
This invention provides a method for producing a stacked ceramic body that does not require strict control of an oxygen partial pressure in a sintering gas. To produce a stacked ceramic body by alternately stacking dielectric layer and electrode layers, an unsintered stacked bodyis prepared by alternately stacking unsintered dielectric layers containing a PZT type dielectric material and unsintered electrode layers containing an electrode material, and is sintered in a sintering gas to which a dielectric layer anti-reducing agentand an electrode layer anti-oxidantare introduced. Alternatively, sintering is conducted in a gas containing only the dielectric layer anti-reducing agentor in a gas containing only the electrode layer anti-oxidant
