PROBLEM TO BE SOLVED: To provide a battery pack in which in a battery module to connect a plurality of battery packs to parallel-connect a plurality of unit cells, if gas is generated from the unit cells, the battery pack or the battery module to include the unit cells can be found easily by observation from outside.SOLUTION: The battery pack 1010 is equipped with the battery module 200 to have the battery pack to parallel-connect the plurality of unit cells and a case to house the plurality of battery packs side by side and a gas exhaust duct 405. The unit cells are equipped with an open part to exhaust gas generated in the unit cells to the exterior. The case has the case body and a lid part, and is sectioned into a housing part to house the battery pack and an exhaust route part to exhaust the gas exhausted from the unit cells to the exterior of the case. The exhaust route part is equipped with an exhaust passage for each battery pack. An exhaust port to communicate the exhaust route part and the gas exhaust duct is formed in the case. A gas trace visible part 500 is installed at the lid part or the gas exhaust duct to form the battery pack 1010. |
