BATTERY PACK

A battery pack includes a plurality of battery blocks each including a gas exhaust surface, the gas exhaust surfaces of the plurality of battery blocks facing each other, and a heat-resistant member arranged between the gas exhaust surfaces facing each other, and forming gas exhaust paths between the heat-resistant member and each of the gas exhaust surfaces facing each other. Each of the battery block includes a plurality of battery cells including a gas exhaust valve, and a holder holding the plurality of battery cells and aligning the gas exhaust valves of the plurality of battery cells on the holder end surface of the holder to form the gas exhaust surfaces. The heat-resistant member is fixed between the holder end surfaces of the plurality of battery blocks. The holder end surfaces face each other. The heat resistant member is displaceable to widen a corresponding one of the gas exhaust paths in response to a pressure of gas exhausted from an abnormal cell among the plurality of cells.
