PROBLEM TO BE SOLVED: To facilitate gas generated from an electrode assembly to be circulated in a case.SOLUTION: A holding tape for holding an electrode assembly in a lamination direction of an electrode is pasted to the electrode assembly. At this time, on a tab side end surface 14c of the electrode assembly having a portion to face a pressure receiving part S of a pressure release valve 90, holding tapes t1 and t2 are pasted by avoiding the portion to face the pressure receiving part S. Thus, a gas circulation path toward the pressure receiving part S is secured.SELECTED DRAWING: Figure 4 |
