Abstract
There is provided a honeycomb type heating device including: a pillar-shaped honeycomb substrate having a partition wall defining a plurality of cells extending from one end face to the other end face and a circumferential wall surrounding the partition wall; a plurality of heaters adjacently arranged on a circumferential face that is an outside surface of the circumferential wall in a circumferential direction of the circumferential face; and intermediate members interposed between the circumferential face of the honeycomb substrate and the plurality of heaters. The sum of areas of portions of the circumferential face covered with the intermediate members between the circumferential face of the honeycomb substrate and the plurality of heaters is 20 to 100% of the sum of areas of portions of the circumferential face covered with the plurality of heaters.
