<p>PURPOSE:To obtain effective purification function by so forming a resistance adjusting means as to be substantially even to a sectional face of a main monorice catalyst on which a sectional face of a heating part of a heater is also provided. CONSTITUTION:Slits 11 as resistance adjusting mechanisms are formed on a honeycomb structure 10, while an inorganic adhesive is charged in an outer peripheral part for insulation. After the honeycomb structure 10 is coated with gamma-alumina, Pd and Pt are respectively held, to prepare a catalyst through burning. Electrodes 13 are set at two portions of an outer wall of the thus obtained honeycomb structure 10 with catalyst. The structure is then arranged in front of a marketed catalytic converter rhodium 14 as a main monorice catalyst, that is, on an upstream side of gas.</p> |
