Battery module

The present invention provides a battery module capable of preventing gas generated from a battery cell under degassing conditions to the outside. A battery module according to the present invention includes a plurality of battery cells arranged in one direction, each with a vent which discharges gas; wherein the battery module includes an insulating member formed on to correspond to the vents; a cover covering the vents and the insulating member and a pressurizing member formed between the cover and the insulating member. The insulating member may include a first opening at area corresponding to the vent and a double protrusion may be formed along a circumference of the first opening of the insulating member facing the vent. Therefore, the sealing capacity of the space in which gas flow path is formed is improved.
