A battery pack includes: a plurality of battery cells; a case providing an accommodation space for accommodating the battery cells and a cooling fluid for cooling the battery cells; and a barrier wall extending across the accommodation space and dividing the accommodation space into an upstream area in communication with an inlet for the cooling fluid and a downstream area in communication with an outlet for the cooling fluid. The barrier wall provides a communication area where the upstream area and the downstream area communicate with each other. The inlet and the outlet are at a first end of the barrier wall in an extension direction of the barrier wall, and the communication area is at a second end of the barrier wall in the extension direction of the barrier wall.
