摘要： A laminate film (100) of the present invention includes a substrate layer (101) ; and a metal oxide layer (103) which is provided on one surface or both surfaces of the substrate layer (101) and contains a metal oxide. Further, the oxygen permeability measured under conditions of a temperature of 20°C and a humidity of 90% RH in conformity with JIS K 7126-2:2006 is 20 ml/m 2 ·day·MPa or less and the water vapor permeability measured under conditions of a temperature of 40°C and a humidity of 90% RH is 2.5 g/m 2 day or greater. In addition, when the K± beam intensity of a metal constituting the metal oxide which is obtained by performing fluorescence X-ray analysis on the metal oxide layer (103) is set to A and the K± beam intensity of the metal which is obtained by performing fluorescence X-ray analysis on a metal layer formed of the metal constituting the metal oxide is set to B, A/B is equal to or greater than 0.20 and equal to or less than 0.97.
