PROBLEM TO BE SOLVED: To provide a power storage device that is able to restrict interference between an electrode terminal and a separator via a conductive member.SOLUTION: In an electrode assembly 14 of a secondary battery 10, a separator 27 is formed by heat-depositing first and second separators opposite to each other. The separator 27 has: an accommodating part for accommodating the portion of a positive pole electrode 21 other than a positive pole tab 31; a deposited part 39 in which parts jutting out towards the respective end edges of both the separators from the accommodating part are heat deposited; and tab opposite parts 27g. Additionally, in the deposited part 39, the separator 27 sandwiches the tab opposite parts 27g in a direction along the first edge 27c of the separator 27. Additionally, in portions facing the terminal side deposited pieces 41c, 42c, the separator 27 has a facing part 39b where the degree of contraction resulting from heat deposition is made higher than that in the other portion. |
