Claims

[Claims for Utility Model Registration] A honeycomb part formed by stacking a flat plate and a corrugated plate and winding them into a roll shape, a wax member wrapped around the outer periphery of the honeycomb part in a cylindrical shape, and a housing in which the honeycomb member is housed. In the metal carrier, the outer circumferential surface of the honeycomb portion and the inner circumferential surface of the outer tube are joined via the brazing member, the boundary between the bonded portion and the non-bonded portion. 1. A metal carrier for an exhaust gas purification catalyst, wherein the metal carrier has a wave shape extending in the circumferential direction, and the length of the boundary portion is longer than the outer circumferential length of the honeycomb portion.
