A deodorizer (A), provided with: a body case (C) having opening intakes (11) and an outlet (42) which open outwards, and having a wind channel (R) communicating from the intakes (11) to the outlet (42) a blower fan (44) internally provided in the body case (C), the blower fan (44) introducing indoor air into the wind channel (R) extending from the intakes (11) to the outlet (42) a deodorizing means (62), provided partway along the wind channel (R), through which the introduced air can pass a heating means (63) disposed so as to face a region representing at least a part of the deodorizing means (62), the heating means (63) heating the deodorizing means (62) at 200°C or below and a controller (47) for controlling the operation of the blower fan (44) and the heating means (63). The deodorizing means (62) is obtained by forming, on a carrier, an adsorbent which does not cause the adsorbed substance to oxidatively decompose and a catalytic component for causing the adsorbed substance to oxidatively decompose, and is prepared so that the rate of conversion of alcohol into acetic acid by the catalytic component is 15% or less on average across the entire deodorizing means (62).Le dispositif de désodorisation (A) de linvention est équipé : dune enveloppe de corps principal (C) qui possède un orifice dadmission (11) et un orifice de sortie (42) souvrant vers une partie externe, et dans laquelle est formé un trajet de ventilation (R) reliant lorifice dadmission (11) à lorifice de sortie (42) dun ventilateur soufflant (44) qui est stocké dans une enveloppe de corps principal (C), et qui introduit lair interne à une pièce dans le trajet de ventilation (R) allant de lorifice dadmission (11) à lorifice de sortie (42) dun moyen de désodorisation (62) qui est agencé de manière intermédiaire dans le trajet de ventilation (R), et qui permet le passage de lair introduit dun moyen de chauffage (63) qui est disposé en opposition par rapport à au moins une partie dune région du moyen de
