To provide a barrier film excellent in gas barrier properties, light shielding properties and water-resistant adhesiveness.SOLUTION: A barrier film comprises a base material layer 11, a first physical vapor phase deposition layer 12, a barrier coat layer 13, and a second physical vapor phase deposition layer 14 in this order. An oxygen plasma treatment surface subjected to oxygen plasma treatment is formed on the base material layer 11, the first physical vapor phase deposition layer 12 is formed on the oxygen plasma treatment surface, and the first physical vapor phase deposition layer 12 is an aluminum oxide deposition film.SELECTED DRAWING: Figure 1
