Honeycomb heater with parallel circuits

摘要

A honeycomb heater includes a honeycomb structure made of an electroconductive material having slits (la,lb) for resistance adjustment and electrodes (3) 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.
