PROBLEM TO BE SOLVED: To prevent shape distortion and wrinkling of the two reed sheets folded to from positive electrode reeds caused by a circumferential difference between the inner and outer sides. SOLUTION: When connecting a positive electrode reed 4 comprising sheets of reed parts 4A, 4B to electrode connector installed on the end of battery and accommodating the positive electrode reed 4 into battery case by folding it, to form in advance a slack part 4C responding to difference of circumference between the inner side and the outer side resulting from the folding on the reed part 4B positioned on the outer side by the folding. |
