1. A battery module comprising:
a battery stack including a plurality of batteries that are stacked, the plurality of batteries including a plurality of valves through which a gas is blown off, the plurality of the valves being disposed on a surface of the battery stack;
a duct plate configured to cover the surface of the battery stack, the duct plate including a gas discharge duct that is elongated and extends in a stacking direction of the batteries, is connected to the valves of the batteries, and temporarily stores the gas blown off through the valves;
a cover plate placed on the duct plate; and
a flow path portion defined by the duct plate and the cover plate, the flow path portion extending from the gas discharge duct in a first direction that intersects with the stacking direction of the batteries and allowing leaking of the gas in the gas discharge duct to an outside of the battery module,
wherein the cover plate is disposed in a state where a predetermined gap is configured between the cover plate and a first wall of the gas discharge duct that faces the valves,
a first opening that allows an inside of the gas discharge duct and the predetermined gap to communicate with each other is configured in the first wall of the gas discharge duct,
the duct plate includes a pair of second walls that is arranged side by side with each of the plurality of valves sandwiched between the pair of second walls in a direction perpendicular to the stacking direction of the batteries and defines the gas discharge duct together with the first wall,
the first wall and the pair of second walls are elongated and extend parallel to one another in the stacking direction of the batteries, and
a second opening that allows the gas discharge duct and the flow path to communicate with each other is configured in the pair of second walls respectively.
