Abstract
Provided are a battery module including a bus bar, whereby weldability may be increased by reducing current loss when welding the bus bar and an electrode terminal of a battery cell, and a battery pack including the battery module. The battery module includes: a plurality of cylindrical battery cells; a module housing; and a bus bar configured to contact the electrode terminals of the plurality of cylindrical battery cells to electrically connect between the plurality of cylindrical battery cells, wherein the bus bar includes: a main body portion that is positioned over or below the plurality of cylindrical battery cells and has a plate shape that is flat in a horizontal direction, wherein at least one coupling opening perforated vertically is formed in the plate shape; and a first connection extension portion and a second connection extension portion that protrude and extend from an internal boundary of the coupling opening in different horizontal directions from each other and have end portions that are electrically connected and fixed to an electrode terminal of one of the plurality of cylindrical battery cells.
