PROBLEM TO BE SOLVED: To provide a biodeodorization device which is free from pressure drop and allows the enhancement of the treatment efficiency of odorous gases. SOLUTION: The biodeodorization device has a container 11 which has an inlet 13 and an outlet 14, deodorizing materials 2 which are housed in the container 11 and containing microorganisms for treating the odorous gases and a humidity sensor 3a and temperature sensor 3b which measure the humidity and temperature of the odorous gases. Porous coarse materials 1 mixed with the deodorizing materials 2 are arranged in the container 11. The porous coarse materials 1 are arranged in the container 11 in the manner described above, by which the pressure drop in the container 11 may be lessened.
