Abstract
In a carrier for a catalyst for purifying exhaust gas, a honeycomb is formed by coiling a corrugated sheet and a flat sheet together, and is mounted in an outer cylinder. An Al (alloy)-clad foil or hot-dip Al (alloy) galvanized foil is used to form the honeycomb, which is heat treated in a vacuum or a reducing atmosphere to simultaneously bond the corrugated sheet and flat sheet together and also bond the honeycomb to the outer cylinder, and to diffuse Al into the foil.
