A method of producing a molded ceramic article comprises the first step mixing powdery raw materials and a liquid additive, thereby obtaining a mixed raw material, the second step press-molding the mixed raw material obtained in the first step in a hydrostatically applied condition of pressure, thereby removing an excess of the liquid additive to obtain a preform, and the third step calcining the preform obtained in the second step to obtain a molded ceramic article. The molded ceramic article comprises, as a principal component, copper and, as essential components, Cr and Ni within composition ranges of 0.1</= Cr< 2 wt. % and 0.1</= Ni< 10 wt. % and further at least one additive component selected from the group consisting of the following composition ratios: the following composition ratios: O<Fe< 5 wt. %, O</=Co< 5 wt. %, O</=Al< 10 wt. %, O</=Ti< 20 wt. %, O</=Mo< 3 wt. %, O</=Si< 3 wt. %, O</=V< 3 wt. %, O</=Mg< 1 wt. % and O</=C < 5 wt % and has at least one composition range selected from the group consisting of the following composition ratios: O<O2<10 wt. %, O<N2<5 wt. % and O<B< 10 wt. %.
