TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: In the formation of first active material layer, the first application liquid is dispensed to the surface of the base material from a first nozzle which relatively moves with respect to the surface of the base material, thus the first application liquid is applied in many lines separated from each other to the surface of the base material. The base material is a laminated body in which a third active material layer containing a third active material having the same polarity as the first active material is formed on a surface of a current collector. In the formation of first active material layer, the first application liquid is applied to the surface of the base material at a side where the third active material layer is formed. The first active material and the third active material have the same or substantially the same composition, where the third active material has a larger specific surface area than the first active material. The method further comprises: forming third active material layer, before the formation of first active material layer, by dispensing a fourth application liquid containing the third active material to the surface of the current collector from a second nozzle which relatively moves with respect to the surface of the current controller, where in the formation of first active material layer a dispense opening of the second nozzle has a larger opening area than a dispense opening of the third nozzle; and laminating a conductive film to laminate a current collector, which will become a current collector corresponding to the second active material, on a layer of the third application liquid in a state where the third application liquid applied in the formation of second active material layer is not yet cured. In the formation of second active material layer, the third application liquid is applied by a knife coating method, a doctor blade method, a bar coating method or a slit coating method. In the formation of electrolyte layer, the second application liquid is applied by a spin coating method or a spray coating method. Preferred Components: The thickness of the electrolyte layer is smaller than a height difference of the uneven pattern of the first active material layer, and the base material is a current collector corresponding to the first active material.
