PROBLEM TO BE SOLVED: To provide a battery module capable of readily connecting a sensor for detecting a state of battery cells and a control device, even when a cover member is arranged.SOLUTION: A battery module 10 comprises battery cells 11, arranged in parallel, which are held in battery holders 12 made of a resin. The battery cells 11 include connection terminals 20, and the connection terminals 20 adjacent to each other in a parallel arrangement direction of the battery cells 11 are connected by bus bars 22. Bolts 23 which penetrate the bus bars 22 screw into screw holes of the connection terminals 20 of the battery cells 11 so that the bus bars 22 are fixed to the connection terminals 20. Voltage detection terminals 24 are arranged between heads of the bolts 23 and the connection terminals 20. The battery module 10 includes a cover member 31 which faces surfaces, of the battery cells 11, where the connection terminals 20 are arranged. The cover member 31 includes a first cover 32 and a second cover 41. Signal transmission lines 25 of the voltage detection terminals 24 pass between the first cover 32 and the second cover 41. |
