PROBLEM TO BE SOLVED: To prevent damage on an electrode assembly 5, when inserting the electrode assembly 5 into a case.SOLUTION: A thread-like member 55 is arranged, at least partially, on the surface of an electrode assembly 5. When inserting the electrode assembly 5 into a case, it is inserted together with the thread-like member 55 so that the thread-like member 55 crosses the insertion direction of the electrode assembly 5. Since the thread-like member 55 rotates between the electrode assembly 5 and the case, friction therebetween can be reduced, and damage on the electrode assembly 5 is prevented. |
