A heater 4 is provided around the box body 8, and an intake port 5 and an exhaust port 6 are provided on the upper side wall and the lower bottom plate of the box body 8, respectively.

In this case, the air sucked into the box 8 from the intake port 5 passes through the honeycomb body 16 in the middle of the ventilation path 3, and at this time, the air is deodorized by the deodorizing catalyst attached to the honeycomb body 16. The odor components in the air are adsorbed and removed, and the deodorized air is exhausted from the exhaust port 6 to the outside of the box 8. Further, at this time, the honeycomb body 16 is heated by the heater 4, so that the deodorizing catalyst attached to the honeycomb body 16 is activated, and the adsorbed odor component is decomposed, thereby improving the deodorizing ability.
