A gas-barrier multilayer film comprising a base and one or more thin layers formed on at least one surface of the base, wherein at least one of the thin layers satisfies that the thin layer satisfies requirements (i) to (iii) concerning a silicon distribution curve, an oxygen distribution curve, and a carbon distribution curve and/or that the thin layer gives an electron beam transmission curve having at least one extreme value. The gas-barrier multilayer film has sufficient gas-barrier properties. Even when bent, the film is sufficiently inhibited from decreasing in gas-barrier properties. The gas-barrier multilayer film is suitable for use in flexible illuminators using organic electroluminescent devices (organic EL devices), organic thin-film solar cells, liquid-crystal displays, etc. L'invention concerne une pellicule multicouche barrière aux gaz comprenant une base et une ou plusieurs couches minces formées sur au moins une surface de la base, au moins une des couches minces étant telle que la couche mince satisfait aux exigences (i) à (iii) concernant une courbe de distribution de silicium, une courbe de distribution d'oxygène, et une courbe de distribution de carbone et/ou que la couche mince donne une courbe de transmission de faisceau d'électrons ayant au moins une valeur extrême. La pellicule multicouche barrière aux gaz présente des propriétés suffisantes de barrière aux gaz. Même lorsqu'elle est courbée, la pellicule est suffisamment inhibée pour voir ses propriétés de barrière aux gaz se réduire. La pellicule multicouche barrière aux gaz peut être utilisée dans les éclairages flexibles utilisant des dispositifs électroluminescents organiques (dispositifs EL organiques) des cellules solaires à couche mince organiques, des affichages à cristaux liquides, etc.
