PROBLEM TO BE SOLVED: To provide a battery pack in which the distribution of cooling air to unit cells in a module case is uniform and good.SOLUTION: A battery pack (1) comprises a battery (18), a plurality of module cases (4-7), a battery pack case (2), and an air blower (8). The air blower (8) radiates air from inside the battery pack case (2) to the open air via an exhaust port (31). At this time, air flows into the battery pack case (2) via an air suction part (3). The air from the air suction part (3) is guided to the inside of each module case (4-7) by a duct (20). The air from the duct (20) is guided to the outside of the module cases (4-7) by flow-out openings (14-17) formed in each module case (4-7). An internal space (30) is provided in which the air from the plurality of flow-out openings (14-17) of each module case (4-7) gathers. |
