To obtain a metallic carrier having oxidation resistance and sufficient strength by performing the joint of a flat plate of a metallic honeycomb body to a corrugated plate thereof and the joint of the metallic honeycomb body to a metallic outer cylinder at projected parts provided on the flat plate.
The honeycomb body 6 having the projected parts 2 on the outer peripheral part is manufactured by providing the projected parts 2 on the flat plate made of a high Al-containing ferritic stainless steel plate, applying a slurry prepared by mixing a fluoride of Al with a water-soluble binder on the front and rear side of the flat plate and laminatingly winding with the corrugated plate 3 formed by bending into corrugated shape. Next, the honeycomb body 6 is forcibly fitted into the ferritic stainless steel plate-made metallic outer jacket, on the inside surface of which plural grooves are provided, by reducing its outside diameter to, e.g. 1.2-1.5mm. After that, the metallic carrier is manufactured by heating in Ar atmosphere in a continuous atmospheric furnace. As a result, the metallic carrier excellent in oxidation resistance and thermal fatigue resistance is obtained.
