  "textContent": "A battery module includes: a plurality of laminated battery cells; a bus bar connected to the battery cells; and a sensor unit electrically connected to the bus bar that measures a state of the battery cells. The bus bar is disposed in an accommodation space formed on one side surface of the laminated cell. The sensor unit includes a sensor case accommodating the sensor circuit, formed to a shape of the bus bar, and accommodated in the accommodation space and in contact with the bus bar. A fitting portion is electrically connected to the sensor circuit facing the bus bar in the sensor case when the sensor case is accommodated in the accommodation space. By fitting the fitting portion to the bus bar, the sensor case is fixed to the bus bar, and the sensor circuit is electrically connected to the bus bar via the fitting portion.",
