PROBLEM TO BE SOLVED: To provide a power storage element capable of minimizing an increase in temperature by suppressing a short circuit between electrodes in an electrode body.SOLUTION: A power storage element includes: an electrode body 2 comprising electrodes laminated therein; a case 3 for housing the electrode body 2; and an insulation member 6 disposed between the electrode body 2 and the case 3. The insulation member 6 includes a plurality of long members that are long in a first direction along the surface of the electrode body 2, a portion of each long member located at least between both ends thereof being movable in a second direction along the surface of the electrode body 2, the second direction intersecting the first direction.SELECTED DRAWING: Figure 3 |
