Abstract
A resistance heater according to the present invention comprises a honeycomb structure having a large number of passages. The honeycomb structure is provided with at least two electrodes through which a current is supplied thereto. The honeycomb structure also has a means to attain a current density of 5 A/mm.sup.2 or above between the electrodes such as slits within the honeycomb structure. A current is supplied between the electrodes at a current density of 5 A/mm.sup.2 or above.
