Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a middle-sized or large-sized battery pack case in which distribution uniformity of coolant flow is improved.SOLUTION: The middle-sized or large-sized battery pack case 70', to which a battery module 32 having a plurality of stacked chargeable and dischargeable battery cells 30 are attached, is provided with a coolant inlet 10' and a coolant outlet 20' so that the coolant can flow in a direction perpendicular to the stacking direction of the battery cell 30, from one side of the battery module 32 to the opposite side thereof. The battery pack case 70' is further provided with a fluid space ("inlet duct" 40') elongating from the coolant inlet 10' to the battery module 32, and other fluid space ("outlet duct" 50') elongating from the battery module 32 to the coolant outlet 20'. Vertical cross-sectional area of the inlet duct 40' is smaller than that of the outlet duct 50'.
