PROBLEM TO BE SOLVED: To provide a technology for suppressing re-electrification of a power storage device after blocking electrification of the power storage device.SOLUTION: A power storage device includes a current blocking device comprising: a partition which is deformed when receiving pressure inside a case; a conduction member having first and second conduction sections adjacent to each other on an electrification path; and an insulation member disposed on the side reverse to a deformation direction of the partition, of the conduction member. The insulation member is disposed over a surface of the first conduction section and a surface of the second conduction section, and includes a first insulation section connected to the first conduction section and a second insulation section connected to the second conduction section. When rise of the pressure inside the case deforms the partition; the first and second conduction sections are separated and the first and second insulation sections are separated, the first conduction section and first insulation section shift to the deformation direction of the partition in conjunction with the deformation of the partition, and the first insulation section shifts between the first and second conduction sections. |
