Abstract: A battery pack includes: a case; a plurality of batteries housed in the case; at least one of a heat-insulating material or an endothermic material disposed between the plurality of batteries; and a fire extinguisher disposed in the case. The heat-insulating material suppresses heat transfer to adjacent batteries when a battery is ignited. The heat-insulating material also blocks heat after the fire is extinguished by the action of the fire extinguisher.
