Abstract
Abstract Disclosed is a conductor paste effective to manufacture a ceramic multilayer structure. The conductor paste comprises an inorganic component containing CuO as a main component and at least one of Cu and Cu 2 O. A multilayer body of the conductor paste and a dielectric paste is subjected to a binder removing process in air, a reduction process in a mixed gas of hydrogen and nitrogen, and a firing process in nitrogen, thereby to obtain a ceramic multilayer structure.
