To provide a deodorizing apparatus that is small in size and can efficiently deodorize a large space. A fluid driving means, a microplasma generating means, and an ozone decomposing / removing means are provided, and the fluid driving means is circulated at a surface wind speed of 1 to 5 m / sec to generate microplasma generating means. 4 includes a pair of ceramic substrates 40, and an electrode is built in each of the pair of ceramic substrates 40. A through hole 41 is formed in each of the pair of ceramic substrates 40 and the built-in electrodes, and the object to be deodorized is formed. Ozone from 0.1 ppm to 10 ppm is generated with respect to the fluid, and the ozonolysis removal means 5 is a catalyst mainly composed of manganese oxide, and is disposed at a distance of 1 cm to 1 m downstream of the microplasma generation means. In the state where ozone is formed together with the microplasma, the fluid to be deodorized passes through the ozonolysis removing means 5. [Selection] Figure 1 |
