Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery pack which cools the interior of a sealed space and prevents breakage and damage of battery cells and modules when a large impact, such as a collision, acts on a vehicle.SOLUTION: A battery pack 14 includes: cells 8; a tray 10 on which the cells 8 are placed; a cover 11 covering the tray 10; and a duct 16 provided in the cover 11 and having a closed cross section 15 through which airflow supplied to the cells 8 and used for cooling passes. The duct 16 has a breaking part which breaks the closed cross section 15 when an external force acts on the cover 11.SELECTED DRAWING: Figure 7 【課題】密閉された空間内を冷却することが可能であると共に、衝突等の車両に大きな衝撃が作用した場合に電池セルやモジュールの破壊や損傷を防止することが可能な電池パックの提供を目的とする。【解決手段】電池８と、電池８が載置されるトレー１０と、トレー１０を覆うカバー１１と、カバー１１の内部に設けられ電池８に対して供給される冷却のための空気流が通過する閉断面１５を有するダクト１６とを備え、ダクト１６は外力が作用した際に閉断面１５を破断させる破断部を有する電池パック１４。【選択図】図７
