[Problem] To provide a microorganism deodorizing device capable of sufficiently exhibiting a decomposing and deodorizing function while suppressing an increase in manufacturing costs even when the device is a large-scale device provided with a large-size deodorizing tank. [Solution] A deodorizing tank 1 of this microorganism deodorizing device 1A is provided with: a deodorizing unit 5 that forms an air flow passage 20 through which air passes from a chamber part 3 to an opening 19 and that is filled with a foaming material 17 in the air flow passage 20; a ventilation-resistance layer 4 that is provided to be close or adjacent to the deodorizing unit 5 and increases the ventilation-resistance of the air flowing through the air flow passage 20; and a chamber unit 3 that is provided to be close or adjacent to the deodorizing unit 5 and/or the ventilation-resistance layer 4 and that is a chamber for temporally reserving air fed to the deodorizing tank 1, wherein in the flow of the air flowing through the air flow passage 20, the ventilation resistance is increased by the ventilation-resistance layer 4, and consequently, the air is fed into the deodorizing unit 5 in a state in which the air is spread over approximately the entire surface of the deodorizing unit 5 in the camber unit 3.
