PURPOSE:To realize non-ozoning by executing simply management of air for passing through an ozone decomposition catalyst, decreasing the quantity of gas passing through the ozone decomposition catalyst and decreasing a load to the ozone decomposition catalyst, and also, lengthening the time for passing through the ozone decomposition catalyst, in the ozone sterilizing device. CONSTITUTION:In the ozone sterilizing device 1, a bypass passage 5 for bypassing an ozone generator 2 is provided, and in the bypass passage 5, an ozone decomposition catalyst 6 is placed, and also, fans 7, 8 for switching the passage by the rotational direction are placed in a state that the ozone decomposition catalyst 6 is inserted and held between each other. |
