PROBLEM TO BE SOLVED: To provide a technique by which efficient deodorizing treatment can be carried out at low cost.SOLUTION: A deodorizing apparatus is provided with a blower for sucking exhaust gas from a channel, an adsorption part having an adsorbing member capable of adsorbing/desorbing odorous substances and a decomposing part that is arranged at the downstream side of the adsorption part and is capable of decomposing the odorous substances. A deodorizing method for carrying out exhaust gas deodorizing treatment by using the deodorizing apparatus includes an adsorbing operation step and a desorbing operation step. The adsorbing operation step includes: an adsorbing step of introducing odorous substance-containing exhaust gas into the adsorption part to adsorb a part of the odorous substances on the adsorbing member; and a first decomposing step of introducing the exhaust gas where the concentration of the odorous substances is reduced by the adsorbing step into the decomposing part to decompose the odorous substances. The desorbing operation step includes: a desorbing step of desorbing the odorous substances adsorbed at the adsorbing step from the adsorbing member; and a second decomposing step of introducing the odorous substances desorbed at the desorbing step into the decomposing part to decompose the odorous substances.
