Disclosed herein is a middle or large-sized battery module including secondary batteries or unit modules, each of which has two or more secondary batteries mounted therein, stacked while being erected vertically, the battery module including a base plate on which the unit modules are stacked in a vertically erected state, a pair of end plates disposed in tight contact with outer surfaces of the outermost unit modules while bottoms of the end plates are fixed to the base plate, and supporting bars connected between opposite sides of upper parts or side parts of the end plates so as to support the end plates, wherein each of the end plates includes a main body contacting a corresponding one of the unit modules, and a top wall, a bottom wall, and a pair of side walls protruding outward from the perimeter of the main body, the thickness of each of the side walls being increased from the top wall to the bottom wall, thereby dispersing pressure (bending load) from the unit modules and the supporting bars.
