PROBLEM TO BE SOLVED: To provide a metal carrier for a catalytic converter intended to prevent a honeycomb core part from falling off resulting from brazing the honeycomb core part with a metal outer cylinder. SOLUTION: This metal carrier for a catalytic converter is provided with a honeycomb core part formed of a roll cylinder of multiple alternate layers of a corrugated plate of and a flat plate of a metal sheet having a rolled flat plate of the metal sheet as the outermost layer and a metal outer cylinder surrounding the outer periphery of the honeycomb core part and bonded to the honeycomb core part with a brazing foil material. The honeycomb core part is characterized in that exhaust gas passages are formed by jointing the corrugated plates with the flat plates through diffusion bonding and by jointing the outermost flat plates together through diffusion bonding to form a zone protected from ingress of a brazing material. |
