Abstract
A power storage device includes an electrode assembly, a case that houses the electrode assembly, and an insulating sheet, which insulates the electrode assembly and the case from each other. The electrode assembly has a layered structure in which positive electrodes and negative electrodes are stacked. The electrode assembly has a first end face, which is orthogonal to the stacking direction, two primary faces, which are located on both sides in the stacking direction, and a tab, which extends on the first end face in the direction orthogonal to the stacking direction. The insulating sheet has a folded box shape, and further has two primary face covering portions, which respectively cover the primary faces of the electrode assembly, and non-primary-face covering portions, which cover the first end face of the electrode assembly and faces other than the primary faces thereof and are continuous with the primary face covering portions. The non-primary face covering portions overlap at least partially with each other.
