BATTERY PACK, MANUFACTURING METHOD OF BATTERY PACK, AND INTERVENING MEMBER

A battery pack includes: a battery module including cells and intervening members; a cooler; and a heat conductive layer provided between heat dissipation surface of the cell and a cooling surface of the cooler. The intervening member includes a second intervening portion to be provided between the heat dissipation surface and the cooling surface. The second intervening portion has a thickness and includes a communicating-passage side wall portion having a tapered shape directed outward along a direction from the heat dissipation surface toward the cooling surface. The heat conductive layer has a layer thickness that is equal to or more than the thickness of the second intervening portion and is filled in at least the communicating passage.
