Zusammenfassung:	PURPOSE: To provide an oxygen indicator sheet which can indicate the reversible adsorption-desorption reaction of oxygen in a short time and can maintain the indication in a reliable state for a long period by giving oxygen permeability to the substrate and either one of the films of the sheet and making the substrate and either one of the films transparent. CONSTITUTION: An oxygen indicator sheet is constituted by forming a poly(ethylene)-cobalt complex film obtained through the reaction between cobalt (II) perchlorate and poly(ethylene imine) on at least part of one surface of a thermoplastic plastic substrate and coating the complex film with a thermoplastic plastic film and giving oxygen permeability to the substrate and either one of the films. In addition, the substrate and either one of the films are made transparent. Therefore, the indicator sheet can indicate the reversible adsorption- desorption reaction of oxygen in a short time and maintain the indication in a reliable state for a long period.
