PROBLEM TO BE SOLVED: To prevent the occurrence of a failure of a metallic carrier by executing brazing on the exhaust gas inflow side of the metallic carrier and diffusion joining on the exhaust gas outflow side thereof in executing joining of the contact part of flat foil and corrugated foil. SOLUTION: A honeycomb body 1 is formed by using stainless steel contg. aluminum and subjecting the flat foil 5 to corrugation to form corrugated foil 6 and alternately winding the corrugated foil 6 and the flat foil 5. The joining of the contact parts of the flat foil 5 and corrugated foil 6 of the honeycomb body 1 is executed by applying an adhesive on the flat foil 5 or the corrugated foil 6 before winding on the exhaust gas inflow side of the metallic carrier 2, sprinkling brazing powder on the honeycomb body 1 after winding to stick the brazing powder to the adhesive coated parts, thereby forming brazied parts 4. The flat foil 5 and the corrugated foil 6 and wound on the exhaust gas outflow side 4 and are subjected to a high-temp. vacuum treatment, by which the contact part of the flat foil 5 and the corrugated foil 6 are diffusion joined and the diffusion joined parts 15 are formed. |
