PROBLEM TO BE SOLVED: To prevent the deterioration of an oxygen indicator having an indicator layer under light irradiation. SOLUTION: An anchor coat layer having light shield property and/or an overcoat layer having light shield property is provided on a base, and then an oxygen indicator layer is stacked on it in the oxygen indicator. In the light shield characteristic of the anchor coat layer/overcoat layer, the transmittance of a wavelength ranging from 350 nm to 500 nm is preferably less than 50%. COPYRIGHT: (C)2003,JPO
