Abstract
A method of manufacturing large-sized laminated dielectrics of high quality which permit adjustment of the atmosphere during sintering process to be accomplished easily, and which can eliminate the problems such as expansion due to reaction with the atmosphere gas. When a laminated body , consisting of oxide dielectric layers and inner electrode layers having a base metal such as Cu as a main component, is sintered in a reducing atmosphere, a mixed gas having CO gas as a main component and containing optional amount of CO gas and O gas is used. By using the equilibrium system of CO ⇄2CO+(1/2)O and adjusting the amounts of CO gas and O gas, oxygen partial pressure in the atmosphere gas can be easily and stably adjusted and fluctuation and variation in the atmosphere can be suppressed.
