Abstract:
A method for manufacturing laminated dielectrics, comprising the step of sintering, in a reducing atmosphere, a laminated body consisting of oxide dielectric layers and inner electrode layers having a base metal as a main constituent, characterized in that said sintering step is performed in a mixed gas having CO2 gas as a main component and containing optional amounts of CO gas and O2 gas, and that oxygen partial pressure in the atmosphere is adjusted to a predetermined range by adjusting the amount of said CO gas and O2 gas,wherein aerating boards formed of a material having no reactivity with said laminated body are provided in generally symmetrical positions on the upper and lower sides, or in a position either on the upper or the lower side, of said laminated body, and in contact with said laminated body.
