Abstract
A battery pack includes a plurality of stacked battery assemblies and an insulating spacer. The battery assemblies are provided with a pair of unit cells stacked in a thickness direction. Each unit cell includes a cell body having a power generation element and a flat shape, and an electrode tab protruding out from the cell body. The spacer is disposed between electrode tabs of the pair of the unit cells holding the electrode tabs and is electrically connected in the battery assemblies. A pair of the electrode tabs has distal end portions electrically connecting adjacent battery assemblies of the battery assemblies to each other. The distal end portions are bent in the stacking direction on a side of a surface of the insulating spacer. The distal end portions are positioned on opposite sides of the cell body. The distal end portions that are bent are electrically connected to each other.
