Summary:To prevent reduction in cooling efficiency of a battery module inside a battery pack.SOLUTION: A battery pack has: a chargeable/dischargeable battery module; and a housing part which houses the battery module. The housing part has a bottom part on which the battery module is placed. The bottom part has: a passage part through which a coolant for cooling the battery module flows; and a heat insulating part provided on the opposite side, across the passage part, to the side where the battery module is placed.SELECTED DRAWING: Figure 4 【課題】バッテリパック内のバッテリモジュールの冷却効率の低下を抑制する。【解決手段】バッテリパックは、充放電可能なバッテリモジュールと、バッテリモジュールを収容する収容部と、を有する。収容部は、バッテリモジュールを載置する底部を有する。底部は、バッテリモジュールを冷却する冷媒が流れる流路部と、流路部に対してバッテリモジュールを載置する側とは反対側に設けられる断熱部と、を備える。【選択図】図４
