Abstract
A battery stack includes a plurality of battery packs and a plurality of spacers. The battery pack each has a case and a sealing plate. The sealing plate is fitted to an inner peripheral surface of an opening of the case. Each of the plurality of spacers is arranged at the center of a flat surface on each side of the battery pack, and a contour of a contact region of the spacer with the flat surface is smaller than a contour of the flat surface of the battery pack. The plurality of spacers and the plurality of battery packs are alternately stacked. The plurality of spacers and the plurality of battery packs are applied with a load in a stacking direction. The center of the flat surface of the battery pack is recessed in a shape of a contour of the spacer by the load.
