To provide a battery pack capable of suppressing impact applied to an assembled battery in a sideward collision, while ensuring cooling performance.SOLUTION: A battery pack comprises: an assembled battery 30; a first duct 41 and a second duct 42 for sending cooling air to the assembled battery 30; and a housing case 20. In a mounted state where the battery pack is mounted on a vehicle, the first duct 41 and the second duct 42 extend along a first direction parallel to the cross direction of the vehicle. Also, in the mounted state, the ducts are arranged with a gap provided therebetween in a second direction parallel to the width direction of the vehicle. The first duct 41 is arranged on the outside of the assembled battery 30 on one side in the second direction, while the second duct 42 is arranged on the outside of the assembled battery 30 on the other side in the second direction.SELECTED DRAWING: Figure 2 【課題】冷却性能を確保しつつ、側突された場合に組電池への衝撃の入力を抑制することができる電池パックを提供する。【解決手段】電池パックは、組電池３０と、組電池３０に向けて冷却風を送出するための第１ダクト４１および第２ダクト４２と、収容ケース２０と、を備える。第１ダクト４１および第２ダクト４２は、電池パックが車両に搭載された搭載状態において車両の前後方向と平行となる第１方向に沿って延在し、かつ、搭載状態において車両の幅方向と平行となる第２方向に間隔を空けて配置されている。第２方向の一方側における組電池３０の外側に、第１ダクト４１が配置されており、第２方向の他方側における組電池３０の外側に、第２ダクト４２が配置されている。【選択図】図２
