Abstract
A battery pack has a cell group and a bus bar. The cell group is stacking a plurality of unit cells in a thickness direction. The unit cells each includes a cell body having a power generation element and a flat shape, and an electrode tab protruding out from the cell body. The electrode tabs have distal end portions bent in a stacking direction of the unit cells. The flat plate shape bus bar connects the distal end portions of the electrode tabs of the unit cells while facing the distal end portions, and electrically connects the electrode tabs of at least two of the unit cells with each other.
