Provided is a composite film which is capable of preventing an adhesive layer from containing moisture therein without causing an increase in the cost, and which is thus capable of preventing an organic EL element from deterioration by stably protecting the element for a long period of time in cases where the composite film is used for sealing of an organic EL device. This composite film is obtained by sequentially laminating a first moistureproof film, a first adhesive layer, a mold release film, a second adhesive layer and a second moistureproof film in this order. |
