Abstract: A power supply device has; a battery stacked body where a plural sheets of battery cells each having a positive electrode terminal and a negative electrode terminal at one surface thereof are stacked; and a plurality of bus bars which connect the electrode terminals in the battery cells adjacently disposed. Each of the bus bars partially has a thin area whose thickness is thinner than a thickness of the other area, and an open window formed in the dun area, and opening a portion thereof. The thin area is formed in an oval shape elongated in the battery cell stacking direction, and the open window extends in a direction along the length of the oval shape. This configuration allows the thin area, above and below the length side of the oval shaped thin area, to be secured as a joining area for laser welding or the like.

Abstract: A plurality of battery cells are connected by a busbar. Electrode terminals of the battery cells each include a protruding portion and a welding surface around the protruding portion. The busbar includes a welding plate portion being in surface-contact with the welding surface and having a cut-away portion for guiding the protruding portion, and an exposure gap that exposes the welding surface between the inner side of the cut-away portion and the protruding portion. The busbar is welded to the welding surface in a predetermined welding width (H) by both of a fillet weld part and a penetration welding portion such that the inner edge of the cut-away portion as the fillet weld part is welded to the welding surface, and the boundary between the busbar and the welding surface is welded by the penetration welding portion.
