ABSTRACT:
A honeycomb heater having integrally formed and/or integrally sintered electrodes constructed of a metallic honeycomb structure having a desired honeycomb configuration, and metallic electrodes which are integrally sintered with the honeycomb structure at predetermined positions thereon. The honeycomb heater having integrally sintered electrodes is manufactured by joining or contacting the electrode-like formed bodies to the formed honeycomb body, and then by sintering the formed honeycomb body with the electrode-like formed bodies attached or contacted thereto. The electrodes are made of the same 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 having integrally formed and integrally sintered electrodes 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.
