PROBLEM TO BE SOLVED: To provide a deodorization apparatus which suppresses an increase in cost by having a simple structure, can reduce an electrical power consumption, can maintain deodorization performance for a long period of time, and maintains deodorization performance for a long period of time by decomposing odor by using an oxidation catalyst and heating the oxidation catalyst by using a heater.SOLUTION: A deodorization apparatus 50 comprises: a heater 1 and a heat propagation fin 2 which carries an adsorbent for adsorbing odor and an oxidation catalyst for decomposing odor on a surface, and is fixed to the heater so as to come into contact with the heater. The plurality of heaters 1 are provided in the heat propagation fin 2 so as to be arranged in a height direction of the heat propagation fin 2, and are arranged so that arrangement density thereof becomes higher toward a lower side of the heat propagation fin 2.
