<p>PROBLEM TO BE SOLVED: To provide a power storage device that is able to restrict a short circuit between electrodes, resulting from thermal contraction of a separator, without adding a heat-resistant material to a separator.SOLUTION: A power storage device 100 accommodating in its external member 7 a laminate 6 in which a positive pole 1 and a negative pole 3 are alternately arranged in layers via separators 5. In the separator 5, the positive pole 1 and the negative pole 3 are alternately arranged in each of areas EA formed by alternately superposing seven first face bodies 25 separated by first bend parts 21 of a first separator 20 and seven second face bodies 35 separated by second bend parts 31 of a second separator 30 such that the directions of folds 23 of the first bend parts 21 of the first separator 20 zigzag folded is orthogonal to the directions of folds 33 of the second bend parts 31 of the second separator 30 zigzag folded.</p> |
