Abstract
A honeycomb-type heating device includes a pillar-shaped honeycomb substrate that has partition walls defining a plurality of cells and that has a circumferential wall surrounding the partition walls; a plurality of heaters adjacently arranged on a circumferential face in a circumferential direction of the circumferential face that is an outer surface of the circumferential wall; a coated wire electrically connecting the plurality of heaters; and a metal case housing the honeycomb substrate and the plurality of heaters. Each of the plurality of heaters has an electrode for energization and is a resistance heating type heater that generates heat due to energization, the metal case has hole parts for protruding the electrodes of respective heaters to the outside of the metal case, and the coated wire electrically connects, outside the metal case, the electrodes of respective heaters protruding to the outside of the metal case from the hole parts.
