PROBLEM TO BE SOLVED: To provide a power storage element having an electrode body which has an elongated separator having an inorganic layer and in which the retention of a capacity or the retention of an output is hardly reduced.SOLUTION: A power storage element comprises an electrode body 2 including substantially rectangular positive electrodes 23, substantially rectangular negative electrodes 24 which are alternately laminated with the positive electrodes 23, and belt-like elongated separators 25A each having a base material layer 251 and an inorganic layer 252 superimposed on the base material layer 251. The elongated separator 25A is disposed between the positive electrode 23 and the negative electrode 24, and the base material layer 251 of the elongated separator 25A confronts the negative electrode 24 between the positive electrode 23 and the negative electrode 24.SELECTED DRAWING: Figure 6 |
