PROBLEM TO BE SOLVED: To provide a manufacturing method of an oxygen detector discolored, corresponding to the amount of oxygen in an atmosphere and is especially satisfactory in color developing capacity. SOLUTION: An oxygen-detecting solution is made to infiltrate in an absorber, capable of being impregnated with a liquid, the absorber impregnated with the oxygen-detecting solution is dried to manufacture the oxygen detecting material, and this oxygen-detecting material is packaged by a packaging member. By having oxygen removed from the inside of the packaging member, in which the oxygen detecting material is sealed, the packaged oxygen detecting material is brought to a hue showing oxygen-free state for manufacturing the oxygen detector. Furthermore, the process of adding a color developing and to the oxygen detecting material is adopted, before the oxygen detecting material is sealed. COPYRIGHT: (C)2008,JPO&INPIT
