A paste of a glazing composition is coated on the entire surface of a ceramic substrate having a metallized metal portion, and the paste-coated ceramic substrate is sintered in a reducing atmosphere, and a glazing layer is formed on the entire surface of the metallized metal portion by utilizing the repellency of the melt of the glazing composition to the metallized metal portion. A glazing composition comprising SiO2, B2O3, BaO, Al2O3 and an alkali metal oxide or a glazing composition comprising SiO2, BaO, Al2O3, CaO and MgO or SrO is used. An acrylic resin syrup, especially an isobutyl methacrylate resin syrup, is used as a binder of a coating paste for forming a glazing layer.
