Busbar and battery module including same

A battery module, comprising:

• a plurality of battery cells;
• a housing configured to accommodate the plurality of battery cells and provided with a side plate on opposite sides in a longitudinal direction of the battery cells;
• the side plate made of an electrically insulating material and configured to allow penetration of electrode tabs respectively to extend from the plurality of battery cells;
• a busbar plate disposed on the side plate and configured to provide electrical connections between the plurality of battery cells through coupling with the electrode tabs;
• and
• a busbar including a body connector having a longitudinal direction and a side edge and configured to be in face-to-face contact with the busbar plate, and a bent connector branched outwardly from the side edge formed along a direction perpendicular to the body connector and electrically connected to an external component, wherein an intersection area, where the bent connector and the body connector intersect, is twisted in a bending direction of the bent connector,
• wherein the bent connector is bent along a folding line parallel to the longitudinal direction of the body connector, and
• wherein the folding line is spaced apart and positioned with a predetermined distance from and parallel to the side edge and extends longer than a width of a the bent connector disposed at a portion where the bent connector branches from the body connector.
