See full text

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.
