A deodorizing apparatus A equipped with an inlet port 11 and an outlet port 42 that are open to the outside includes: a body case C including thereinside an air flow passage R communicating from the inlet port 11 to the outlet port 42 a blower fan 44 built in the body case C so as to introduce room air into the air flow passage R from the inlet port 11 to the outlet port 42 a deodorizing means 62 that is disposed in the air flow passage R, and allows introduced air to pass therethrough a heating means 63 disposed opposite to at least a region of the deodorizing means 62 so as to heat the deodorizing means 62 at a temperature of 200 DEG C or less and a controller 47 that controls operations of the blower fan 44 and of the heating means 63. The deodorizing means 62 includes a support on which an adsorbent material that does not oxidatively decompose absorbed substances, and a catalyst composition that oxidatively decomposes the absorbed substances are formed, and the deodorizing means 62 is prepared such that the conversion rate of alcohol to acetic acid obtained by using the catalyst composition becomes 15% or less on average through the entire deodorizing means 62.
