PROBLEM TO BE SOLVED: To provide a compact, light, strong, and high quality battery for which molding process failure is previously inspected, by arranging an anode electrode and a cathode electrode on respective both surfaces of solid-high- molecular electrolyte film, and interposing a separator having a slit between a plurality of laminated battery stacks. SOLUTION: A 0.1 mm wide, for example, slit 28 is provided around the outer surface of an air groove 27 of a separator substrate 26, and therefore, bow or distortion generated in the separator substrate 26 by press machining can be suppressed less. In addition, thickness of a separator 25 is set thicker than 0.2 mm, for example, therefor, an assembling work is easier, a battery stack can be lightened or compacted, and a manufacturing cost is reduced. Defectives such as cracks generated during the pressing and defectives in a coating generated during coating are quickly found by a non-destructive inspection, the fact can be reflected on improvement of the manufacturing conditions, and the highly reliable separator 25 is provided. |
