PROBLEM TO BE SOLVED: To miniaturize an electric device for supplying battery voltage. SOLUTION: A flat winding electrode body 25 having a positive electrode 21 and a negative electrode 22 is accommodated in an armor can 32 having an appearance of a rectangle wherein widths of side surfaces 30A and 30B adjacently provided are different. A non-aqueous electrolyte as a medium of ionic conduction between the positive electrode 21 and the negative electrode 22 is injected through an injection hole 44 which is provided on an outer peripheral part of the wider side surface 30A which is deformed to expand so that a central part rises highest in an ordinary using condition. The injection hole 44 is sealed by a sealing member 41. Thus, the sealing member 41 is disposed on the wider side surface 30A of the armor can 32 so that the sealing member 41 is prevented from projecting outward than the rising of the central part. It is possible to provide a space for accommodating the battery in the electric device for supplying battery voltage in accordance with a shape of the armor can 32. Thus, the electric device for supplying battery voltage can be miniaturized. |
