<p>PROBLEM TO BE SOLVED: To provide a battery module capable of miniaturization while being equipped with a current monitoring function.SOLUTION: A battery module 1 comprises: a cylindrical battery group 2 formed by connecting a plurality of arrayed cylindrical batteries 20; a case 7; and a positive side output terminal 3 and a negative side output terminal 4 pulled out of the upper surface of the case 7. A current monitoring board 5 on which a current sensor that monitors an output current is provided is included. The cylindrical battery group 2 is formed by connecting electrode ends 21 at one side in the axial direction of a plurality of cylindrical batteries 20 to each other and electrode ends 22 at the other side in the axial direction of a plurality of cylindrical batteries 20 to each other with connector tabs 24 and 25 at a plurality of points, respectively. The current monitoring board 5 is located between the electrode ends 21 at one side in the axial direction of the cylindrical battery group 2 and one side surface of the case 7.</p> |
