Abstract
Disclosed herein is a bus bar for electrically connecting electrode leads of unit modules or battery cells (unit cells) in a battery module through a coupling method employing laser welding. Each of the electrode leads and the bus bar has a plate-shaped structure and a protrusion projecting toward the electrode leads is formed on the bus bar at a portion thereof, which is to be welded to the electrode leads through laser irradiation, to allow the portion of the bus bar, which is to be welded to the electrode leads, to be brought into close contact with the electrode leads.
