PROBLEM TO BE SOLVED: To provide a power storage device in which an insulation film is unlikely to be torn and an insulation property of a case of a power storage element is unlikely to be reduced by vibrations or deformation of a constituent member.SOLUTION: A power storage device includes: at least one power storage element including an electrode body and a case for accommodating the electrode body; a space neighboring to a case 10; and a holding member for holding the power storage element and the spacer. The power storage element includes an insulation film 12 that covers an outer surface of the case 10, the insulation film 12 being adhered to at least a portion on the outer surface of the case 10. The spacer has at least an edge or a corner at a position in contact with the outer surface of the case 10 via the insulation film 12. The insulation film 12 is adhered with an adhesion region included in a counter region that is opposite to the spacer, on the outer surface of the case 10, and overlapped with at least the edge or the corner in a direction where the power storage element and the spacer are arranged side by side.SELECTED DRAWING: Figure 4 |
