BATTERY MODULE

A battery module as an example of an exemplary embodiment includes a cooling path for cooling and guiding a gas ejected from an exhaust valve to an outside of the battery module. The cooling path is formed such that temperature T (° C.) of the gas at a path outlet is lower than or equal to 500° C. The cooling path is provided with at least one of a filter having opening size A (mm) of smaller than or equal to 3.5 mm or a baffle plate having opening size A (mm) equivalent to smaller than or equal to 3.5 mm for limiting a size of an ejected object included in the gas when temperature T is higher than or equal to 350° C.
