Abstract

[PROBLEM] To provide a battery pack capable of reducing the size of a device. [SOLUTION] The battery pack (100) comprises a cell group (100G), a bus bar (131), and a terminal member (anode side terminal (133) or cathode side terminal (134)). The cell group (100G) is obtained by stacking, in the thickness direction, a plurality of unit cells (110) provided with a cell body (110H), which includes a power generation element (111) and is formed into a flat shape, and an electrode tab (113) protruding out from the cell body, and the electrode tabs (113) are arranged along the stacking direction. The bus bar is formed into a flat plate shape and joined to the electrode tabs of the unit cells, and it electrically connects the electrode tabs of at least two of the unit cells with each other. The terminal member is joined to the bus bar and relays the input and output of electric power in the cell group. Here, the battery pack is configured such that a terminal joining position where the terminal member is joined to the bus bar is disposed away from the joining position between the bus bar and the electrode tabs, when viewing the surface on which the electrode tabs are arranged in the cell group from a direction that is orthogonal to the surface.
