BATTERY MODULE HAVING HEAT CONDUCTION PAD

A battery module includes: a plurality of cylindrical battery cells each having electrode terminals respectively at an upper portion and a lower portion thereof; a module housing including an accommodation portion having hollow structures in which the cylindrical battery cells are inserted and accommodated; a current collecting plate on an outer surface of the module housing and including welding holes through which the electrode terminals of the cylindrical battery cells are exposed to the outside; a bus bar in contact with each of the electrode terminals and the current collecting plate to electrically connect the electrode terminals to the current collecting plate; and a heat conduction pad disposed outside the current collecting plate and including a contact protrusion portion protruding and extending in a direction in which the electrode terminals are disposed to be in contact with a contact connection portion between the electrode terminals and the bus bar.
