PROBLEM TO BE SOLVED: To enable suitable fixing of an electrode assembly.SOLUTION: A fixing tape 45 contains a first fixing tape 46 extending over an upper end 12c of an electrode assembly 12, a second fixing tape 47 extending over a lower end 12e of the electrode assembly 12, and a third fixing tape 48 extending over side ends 12d, 12f of the electrode assembly 12. The first fixing tape 46 is disposed at the outside of the projecting positions of a positive tab 24 and a negative tab 28 at the upper end 12c of the electrode assembly 12. With respect to each of the first fixing tape 46, the second fixing tape 47 and the third fixing tape 48, one or more pairs of fixing tapes are disposed for the electrode assembly 12 so as to partially cover the upper end 12c, lower end 12e and side ends 12d, 12f of the electrode assembly 12 and be symmetrical in the extension direction of the upper end 12c with respect to a center line extending vertically from the center point of the upper end 12c. |
