The whole of a conductive material layer is formed on a bonding surface of an outer film having flexibility and barrier properties to prepare a composite body in which the conductive material layer is integrated with the outer film. A current collector is located within an application region, and at least a part of an electrode terminal is located outside the application region. A positive electrode active material precursor layer, an electrolyte precursor layer, and a negative electrode active material precursor layer are added to the composite body with plane positions thereof aligned with that of the current collector. These precursor layers are subjected to a crosslinking process. The application regions are applied, and the outer films are bonded, to seal a cell. The crosslinking process may be omitted.

Fumaric acid derivatives and ophthalmic lenses using them are disclosed. More specifically, a fumaric acid derivative having a hydrophilic group and a silicon-containing alkyl group within a molecule, and contact lenses or intraocular lenses using the same are disclosed. The fumaric acid derivatives of the present invention provide, on one hand, superior oxygen permeability by having a silicon-containing alkyl group within the molecular structure, and on the other hand, improved compatibility with other hydrophilic monomers by having a hydrophilic group within the same molecule. When ophthalmic lenses obtained by polymerizing monomer compositions containing the fumaric acid derivative are constructed as, for example, water content lenses, lenses with high oxygen permeability independent from the water content may be obtained, wherein the fumaric acid derivatives is superior in compatibility with the hydrophilic monomer used in combination and allows the combination in various mixing ratios.
