PROCESS FOR PRODUCING CERAMIC MEMBER, CERAMIC MEMBER, GAS SENSOR ELEMENT, FUEL CELL ELEMENT, FILTER ELEMENT, LAYER-BUILT PIEZOELECTRIC ELEMENT, INJECTOR, AND FUEL INJECTION SYSTEM

摘要

A ceramic member is produced which has sufficiently sintered metallic layers and in which the metallic layers are reduced in the content of an impurity residue such as a resin and have a high porosity. The production process comprises a step in which a layered molding comprising two or more metallic paste layers containing a metallic ingredient (M₁) and superposed through a ceramic green sheet is produced and a step in which this layered molding is burned. When the mass proportion of the metallic ingredient (M₁) to all metallic ingredients contained in the metallic paste layers is expressed by X, then at least one of the metallic paste layers is a second metallic paste layer which is higher in mass proportion X than a first metallic paste layer adjacent thereto in the layer superposition direction and the second metallic paste layer contains ceramic particles.
