A battery pack includes battery modules each having a battery cell and a battery case housing the battery cell therein. The battery modules are stacked in a stacking direction so that a cooling passage for allowing a cooling medium to flow is defined between opposed surfaces of adjacent battery cases. One of the opposed surfaces has first ribs projecting toward the other of the opposed surfaces and extending parallel to each other along the one. The other of the opposed surfaces has second ribs projecting toward the one of the opposed surfaces and extending parallel to each other along the other. In the cooling passage, the first ribs and the second ribs intersect each other and end portions of the first ribs and end portions of the second ribs are in contact with each other in the stacking direction.
