    摘要： A vapor deposition film has a vapor deposition layer composed of a metal or an inorganic oxide formed on at least one side of a resin layer (A) which is composed of a resin composition (1). The resin composition (1) is a polyglycol acid containing not less than 70% by mole of a specific structure (a structure represented by formula (1)) as a repeating unit. The surface on which the vapor deposition layer is deposited has a center line average roughness of 5-50 nm. The vapor deposition film has excellent gas barrier properties, excellent workability and decomposition resistance sufficient for practical use.
