In a battery pack for an electric vehicle, since a cooling air suction port (48a) is provided in the vicinity of an end part, on the downstream side in a direction of flow of cooling air, of a battery case (24) so as to oppose the direction of flow, cooling air is in full contact with the battery case (24) before flowing into the cooling air suction port (48a), and dust or water contained in cooling air can be made to adhere to the battery case (24) and removed, thus preventing dust or water from entering the interior of the battery case (24). In particular, since the battery case (24) includes a projecting portion (39a) that rises on the upstream side in the direction of flow of the cooling air suction port (48a) and disturbs the flow of cooling air, and an upper end of the projecting portion (39a) is at a position higher than that of the cooling air suction port (48a), it is possible to reliably put cooling air in contact with the projecting portion (39a) of the battery case (24), thus enhancing the effect in removing dust or water.
