PROBLEM TO BE SOLVED: To provide an exhaust gas purification device which has electrodes excellent in heat resistance, oxidation resistance under a high temperature, and corrosion resistance in an exhaust gas atmosphere. SOLUTION: The exhaust gas purification device 1 includes a carrier 20 which supports a catalyst, and the electrodes 30, 40 provided on an outer surface of carrier 20, wherein the carrier 20 is heated by energization through the electrodes 30, 40 to raise the temperature of catalyst up to the activity temperature. The electrodes 30, 40 comprise one alloy selected from Co-Ni-Cr alloy, Co-Mo alloy, Ni-Cr alloy, Ni-Cr-Mo, and Fe-Ni-Cr alloy. COPYRIGHT: (C)2011,JPO&INPIT |
