Abstract
Abstract A manufacturing method for a multilayered ceramic body using Cu, Ni, Co or Fe as a conductor material, and a conductor forming paste of a particular composition of CuO, NiO, CoO or Fe2O3 as the main component, the paste being applied to the multilayered body. The manufacturing method comprises: a process of forming the multilayered body with conductor paste of CuO, NiO, CoO or Fe2O3 as the main component and insulating paste formed of glass and/or ceramic, so that a binder is removed from the laminate by heat treatment in an oxidizing atmosphere; a process of heat treatment for reducing the oxide; and a sintering process for sintering the laminate in a nitrogen atmosphere.
