PROBLEM TO BE SOLVED: To provide: a gas barrier film for a device, which has a high gas barrier property and which is arranged so that a moisture that a base film contains or an outgassing component from an adhesive layer can be suppressed from going into an organic EL layer; and an organic EL device arranged by use thereof.SOLUTION: A gas barrier film for a device comprises a laminate arranged by putting together at least two gas barrier films each having a base film and a first gas-barrier layer formed on one face of the base film with an adhesive layer interposed therebetween. In the laminate, a plurality of pore portions are formed in the first gas-barrier layer of the uppermost gas barrier film. On a face of the first gas-barrier layer with the plurality of pore portions formed therein, at least a planarization layer and a second gas-barrier layer are laminated in this order.SELECTED DRAWING: Figure 1 【課題】高いガスバリア性を有し、且つ、基材フィルムの含有水分や接着層のアウトガス成分が有機ＥＬ層へ浸入することを抑制したデバイス用ガスバリア性フィルム及びこれを用いた有機ＥＬデバイスを提供する。【解決手段】基材フィルムと前記基材フィルムの一方の面上に形成された第１ガスバリア層とを有するガスバリア性フィルムを少なくとも２枚以上、接着剤層を介して貼り合せた積層体において、最上層のガスバリア性フィルムの第１ガスバリア層に複数の空孔部が形成されており、空孔部が形成された第１ガスバリア層の面上には、少なくとも平坦化層と第２ガスバリア層とがこの順に積層されてなるデバイス用ガスバリア性フィルム。【選択図】図１
