Beschreibung
Zusammenfassung:	[Object] To improve the adhesion of a vapor-deposited film to a substrate.[Solution] A barrier film includes a substrate containing polyester and a vapor-deposited film containing aluminum oxide. At least the elemental bond of A1203 and the elemental bond of CN are detected by etching the barrier film using time-of-flight secondary ion mass spectrometry from a side adjacent to the vapor-deposited film. The peak intensity of the peak of the elemental bond of CN detected at the interface between the substrate and the vapor-deposited film is 0.15 or more times the maximum intensity value of the elemental bond of A1203.
