ABSTRACT:
A honeycomb heater including a honeycomb structure which is made of a conductive material and which has a number of passages substantially parallel to a gas flow direction partitioned by partition walls and which has respective providing a gas inlet and a gas outlet, and at least two electrodes for electrification provided on the honeycomb structure. The honeycomb heater is characterized in that besides the passages, orifices which have a larger hydraulic diameter than the passages and which narrow a current flow path are formed at predetermined positions of the honeycomb structure to adjust resistance, whereby a specific region of the honeycomb heater is locally heated more quickly as compared with other regions at the time of the electrification.
