Abstract:
This battery pack comprises: a plurality of batteries that each have a container accommodating a charging-discharging body and an electrolyte solution and having a gas discharge part provided to one surface thereof, and that are each stacked such that the one surfaces of the respective containers line up on the same plane; a first flow path part that is made of metal, is disposed so as to face the surfaces to which the gas discharge parts are provided, and constitutes a flow path for gas discharged from the gas discharge part of each of the plurality of batteries; a second flow path member that forms a second flow path part having a smaller flow path cross-sectional area than that of the first flow path part; a connection part that connects the first flow path part and the second flow path part via an opening provided in the first flow path member; and a guide member that partitions a space inside the connection part and facing the opening.　This configuration enables the efficient release of gas.
