    Abstract: Provided is a battery module having improved sealing properties of a cooling duct. The battery module includes a battery stack, in which an inlet of an air flow path is opened at one side and an outlet of the air flow path is opened at another side, and a plurality of cooling ducts combined to two side portions of the battery stack to respectively communicate with the inlet of the air flow path and the outlet of the air flow path. At least one of the plurality of cooling ducts includes a plug accommodating part defining a through hole, and a harness accommodating plug air-tightly inserted into the through hole and having a plurality of wire accommodating holes. The harness accommodating plug passes a wire of the internal harness or a wire of the external harness through the wire accommodating hole. The internal harness and the external harness are electrically combined around the harness accommodating plug.
