Abstract
A power storage device comprises: a cell group in which a plurality of battery cells each having a terminal on a first surface are stacked; a cylindrical housing part that houses the cell group; a first plate member extending from the first surface of each of the battery cells in the cell group to side surfaces of each of the battery cells, the side surfaces being adjacent to the first surface, the first plate member being housed in the housing part together with the cell group; a cell side protrusion portion protruding from a portion extending on each of the side surfaces of each of the battery cells toward an inner wall surface of the housing part in the first plate member; and an insertion member that is press-fitted to contact both of the cell side protrusion portion and the inner wall surface disposed closer to the first surface side than the cell side protrusion portion, and presses the cell group against an opposite side of a side facing the first surface via the cell side protrusion portion.
