ABSTRACT:
A resistance adjusting type heater including a honeycomb structure with at least two electrodes provided thereon to supply a current to the honeycomb structure and with resistance adjusting elements provided between the electrodes. The resistance adjusting elements are formed such that a cross-section of a heating portion of the heater is substantially the same as that of a main monolithic catalyst. A catalytic converter includes the resistance adjusting heater which is disposed upstream of a main monolithic catalyst or between main monolithic catalysts. Also, the catalytic converter includes a resistance adjusting heater which is disposed downstream of a main monolithic catalyst. This resistance adjusting heater comprises a honeycomb structure with a catalyst carried thereon, with at least two electrodes provided thereon to supply a current to the honeycomb structure and with a resistance adjusting elements provided between the electrodes. The resistance adjusting elements are formed such that the cross-section of a heating portion of the heater is substantially the same as that of the main monolithic catalyst.
