ABSTRACT:
A honeycomb heater includes a honeycomb structure made of an electroconductive material having slits for resistance adjustment and electrodes fitted thereto for electrification thereof. The slits are formed in the honeycomb structure in such a manner that parallel electric circuits are formed in the honeycomb structure upon electrification of the structure. This honeycomb heater with slits has a low resistance and excellent durability to repeated electrification, and is suitable for use with a battery.
