A deodorization apparatus comprises: a case body 2a formed therein with an air-flow passage 2i through which air flows; first and second lamp units 8, 10 disposed in an air-flow passage in the case body and adapted to generate ozone; first, second and third photo-catalyst filters 7, 9, 11 disposed in the air-flow passage in the case body and provided with photo-catalyst filters; and an impregnated carbon disposed on the downstream side of at least one of the first and second lamp units 8, 10 and the photo-catalyst filters and formed by impregnating an activated carbon adsorbing an odor component with at least one component of iron oxide, potassium hydroxide, nickel nitrate. According to this structure, the deodorization effect at the one passing of the contaminated air, in the air-flow passage, containing odor component is improved, the usable life time can be elongated, and the maintenance of the impregnated carbon, can be simplified.
