Abstract
The present invention relates to a battery case which is made from a steel material, thereby providing a cross-section similar to that of an extruded material and having improved impact resistance properties, and at the same time, enabling the reduction of costs through the integration of components, the battery case comprising a case main body having a plate and a lateral frame enclosing the plate, wherein the lateral frame comprises a hollow part inside thereof, a reinforcement part which traverses the hollow part at a portion between side walls on both sides, or protrudes into the hollow part from at least one of the side walls, and a shock absorption part which is formed by the reinforcement part being bent or curved.
