A honeycomb heater comprises a honeycomb structure (10) having a desired honeycomb configuration, and electrodes (13) which are formed integrally with the honeycomb structure at predetermined positions thereon. The honeycomb heater is manufactured by joining or contacting electrode-like formed bodies (13) to the formed honeycomb body (10), and then sintering the formed honeycomb body with the electrode-like formed bodies attached or contacted thereto. The electrodes are made of the same sinterable material as that of the honeycomb body, or of a material having an electric resistance lower than that of the material comprising the honeycomb body. Alternatively, the honeycomb heater is manufactured by preparing an extrusion of a honeycomb body as one body which has a honeycomb configuration and an electrode-like shape at predetermined positions thereon, and then sintering that formed honeycomb body. <IMAGE> |
