ABSTRACT:
A vessel (102) containing a detector solution (101) is prepared. The detector solution (101) is an aqueous solution prepared by dissolving a detector component containing a dye which changes its color when reacting with ozone gas, a humectant, and an ultraviolet absorber having a hydrophilic group. A prepared sheet-like carrier (103) is dipped in the detector solution (101) for, e.g., 30 sec, thereby forming an impregnated sheet (104) by impregnating the sheet-like carrier (103) with the detector solution (101). The impregnated sheet (104) is then dried by evaporating the solvent (medium) such as water contained in the impregnated sheet (104), thereby forming a sheet-like ozone detecting device (105).
