Abstract

Provided are a honeycomb type heating device capable of causing a honeycomb substrate to come into face-contact with a heater in a wide range and of heating a target even when a part of the heater is broken and a method of using the same. The honeycomb type heating device includes: a pillar-shaped honeycomb substrate 2 which includes a porous partition wall defining a plurality of cells extending from one end face to the other end face and a circumferential wall 3 surrounding the partition wall; and a plurality of heaters 9 which are disposed adjacently in a circumferential direction of an outer circumferential face 8 that is an outer surface of the circumferential wall 3, on the outer circumferential face 8. Each heater 9 is a resistance heating heater which radiates heat by a current supplied thereto, each heater 9 comes into face-contact with the outer circumferential face 8, and a ratio of a total area of a portion covered by the heaters 9 of the outer circumferential face 8 with respect to the entire area of the outer circumferential face 8 is 50 to 100%.
