<P>PROBLEM TO BE SOLVED: To solve the problem that a device possessing an electrical control part for preparing sterilized water containing hypochlorous acid or chlorine dioxide as a main component is often installed at an undesirable place where the device is dewed with condensate or splashed with water because the place of using such sterilized water is mostly located at such an undesirable place although installation of the device in such an undesirable place is not desirable because the device has an electrical control part, and provide a device not having the electric control part. Ž<P>SOLUTION: In a method for preparing sterilized water containing weak acidic hypochlorous acid or chlorine dioxide as a main component by mixing sodium hypochlorite or sodium chlorite with water and then mixing carbonic acid gas therein without any electrical control part, the amounts of sodium hypochlorite and sodium chlorite added, and the amount of carbonic acid gas mixed are automatically controlled corresponding to change of a flow rate of a main fluid so that chlorine and carbonic acid can be kept at a predetermined concentration even when the amount of the sterilized water discharged changes.
