Abstract
A battery pack includes a cell group, a bus bar and a terminal member. The cell group includes a plurality of unit cells stacked in a thickness direction. Each of the unit cells includes a battery main body having a power generation element and a flat shape, and an electrode tab protruding out from the battery main body and arranged along a stacking direction. The bus bar is joined to the electrode tabs and electrically connects the electrode tabs. The terminal member is joined to the bus bar to transfer input and output of electric power in the cell group. The terminal member is joined to the bus bar at a terminal joining position that is spaced away from a joining position between the bus bar and the electrode tabs when viewing a surface on which the electrode tabs are arranged from a direction that is orthogonal to the surface.
