Abstract
An oxygen detecting multilayer body allows easy detection of a color change of an oxygen detecting layer, and prevention of crazing of an oxygen detecting layer. The oxygen detecting multilayer body includes a transparent resin layer, a heat seal layer, and an oxygen detecting layer containing an oxygen detecting component, placed occupying a part of a space between the transparent resin layer and the heat seal layer, wherein a spacer is placed to occupy at least a part of a space between the transparent resin layer and the heat seal layer, where the oxygen detecting layer is not provided, so as to make up a missing thickness of the oxygen detecting multilayer body, wherein the thickness of the oxygen detecting layer is from 0.5 to 40 μm, and the ratio of the thickness of the oxygen detecting layer to the thickness of the spacer is from 15:1 to 1:10.
