Abstract
A metallic carrier for automobile exhaust gas purification made of thin metal foil includes a honeycomb unit composed of 8-25 &mgr;m thick corrugated metal foil and flat metal foil joined by solder joints not fewer than 70% of which have a thickness of at least 1.5 times and not greater than 4 times the foil thickness. A method of producing the metal carrier includes a step of forming a honeycomb unit in which 8-25 &mgr;m thick corrugated metal foil and flat metal foil are joined by solder joints using a solder powder, the solder powder having a particle diameter not greater than 4.5 times the thickness of the metal foil constituting the honeycomb unit.
