Abstract
A power supply device including a plurality of battery cells electrically connected with each other by bus bar. The power supply device has a structure where bus bar includes: rod having conductivity and extending in an arrangement direction of the battery cells; and arm being elastically deformable and being connected to rod, arm is configured such that distal end of arm is welded to an electrode terminal of the battery cell, and rear end of arm is connected to rod so as to electrically connect the plurality of battery cells to each other via the rod, arm is formed of a conductive plate that is elastically deformable, deformation gap extending from rear end toward a distal end is formed between arm and rod, and arm is elastically deformable so as to displace distal end to be welded to the electrode terminal.
