PROBLEM TO BE SOLVED: To stably maintain a high gas barrier property by using a base film having excellent dimensional stability, and having good transparency, moisture resistance, impact resistance, hot water resistance, tight adhesion, etc. An object of the present invention is to provide a barrier film provided and a laminate using the same. In a barrier film in which a composite gas barrier layer composed of a vapor-deposited layer made of an inorganic oxide and a gas barrier composite polymer layer is laminated on one surface of a base film, the base film is the base film. When a load of 0.05 to 0.15 N / mm is applied to the material film and the temperature is raised to 25 to 200 ° C. at a rate of temperature increase of 5 ° C./min, the dimensional change rate in the vertical direction and the horizontal direction is respectively A barrier film using a biaxially stretched polyester resin film in the range of -5.0 to -2.0% and -1.0 to + 1.0%, and a laminate using the same It is about.
