PROBLEM TO BE SOLVED: To provide a deodorization machine in which whole of a large catalyst filter can be efficiently heated by a small size heater without mounting a rolling mechanism, and that has inexpensive price and few failures.SOLUTION: A deodorization machine includes: a catalyst filter 33; and a heating part that heats the same, and the heating part includes: a PTC heater 352 that performs heat evolution by electric power from a lead wire 352c; and a part to be contacted which the PTC heater 352 contacts, and includes: a heat radiation plate 351 that performs face counter to the catalyst filter 33 and performs heat radiation to heat transferred from the PTC heater 352 through the part to be contacted; and a heater holding part 353 that holds the PTC heater 352 in a state contacting the part to be contacted, the heater holding part 353 includes: a contact face 352a of the PTC heater 352; a lead wire drawer face; a cover part 353a that at least covers whole of a heater side face excluding an opposite surface of the same; and a heat transmission part that performs heat transmission to heat from a PTC heater 352 side face through the cover part 353a to the heat radiation plate 351. |
