Abstract: To provide a functional device suitable for dye-sensitized solar cells and the like and having a structure suited for thickness reduction, and a method for making the same with good productivity. A dye-sensitized photovoltaic device 10 is constituted by a transparent substrate 1 formed of glass or the like, a transparent conductive layer 2 formed of FTO or the like, semiconductor electrode layers (negative electrodes) 3 supporting a photosensitizing dye, an electrolyte layer 4, a film-shaped counter electrode (positive electrode) 5, a film-shaped packaging member 6 replacing a counter substrate of the related art, a sealing member 7, power-collecting wiring 8, a wiring protecting layer 9, and the like. As the material of the film-shaped packaging member 6, a material that has high barrier property of suppressing passage of solvents, gasses, water, and the like and excellent resistance to organic solvents and heat is preferred.
