Zusammenfassung:	To weld a bus bar and an electrode terminal with certainty by bringing the bus bar and the electrode terminal into close contact with each other without forming a gap between the bus bar and the electrode terminal, provided is a power supply device that is a power supply device including a plurality of battery cells electrically connected with each other by bus bar (3). The power supply device has a structure where bus bar (3) includes: rod (4) having conductivity and extending in an arrangement direction of the battery cells; and arm (5) being elastically deformable and being connected to rod (4), arm (5) is configured such that distal end (5x) of arm (5) is welded to an electrode terminal of the battery cell, and rear end (5y) of arm (5) is connected to rod (4) so as to electrically connect the plurality of battery cells to each other via the rod, arm (5) is formed of a conductive plate that is elastically deformable, deformation gap (6) extending from rear end (5y) toward a distal end is formed between arm (5) and rod (4), and arm (5) is elastically deformable so as to displace distal end (5x) to be welded to the electrode terminal.
