NOVELTY - An electronic module (10) consists of a water-vapor barrier film (18), a peripheral sealing material (14), an electronic device (12), and a flexible substrate (20). The peripheral sealing material is provided in the periphery of the flexible substrate and the electronic device. The water-vapor barrier film is formed in the region of the peripheral sealing material. The square root of 2 times the diffusion coefficient (K) of the peripheral sealing material is 0.1 cm/(root)hours or less. The water-vapor barrier film consists of inorganic layers formed on a support material (24).    USE - Electronic module is used as flexible thin film solar cell.    ADVANTAGE - The electronic module has excellent sensitivity, durability, and deterioration-proof property, and reduced moisture permeability, and provides the solar cell having organic electroluminescent or solar cell element with excellent reliability.    DETAILED DESCRIPTION - An electronic module consists of a water-vapor barrier film, a peripheral sealing material, an electronic device, and a flexible substrate. The electronic device is formed on the flexible substrate, and the flexible substrate does not permeate the water vapor. The peripheral sealing material is provided in the periphery of the flexible substrate and the electronic device. The water-vapor barrier film is formed in the region of the peripheral sealing material. The square root of 2 times the diffusion coefficient (K) of the peripheral sealing material is 0.1 cm/(root)hours or less. The water-vapor barrier film consists of one or more inorganic layers formed on a support material. The support material is arranged on the surface of peripheral sealing material, and contains a transparent resin.
