VOLTAGE MONITORING MODULE AND BATTERY UNIT

To provide a voltage monitoring module with a structure that enables connection terminals to follow the movement of a cell terminal well even when an amount of movement of the cell terminal due to contraction or expansion of a battery cell is large.SOLUTION: A voltage monitoring module 100 of this embodiment has a flexible printed circuit board 10 having a plurality of wires 51, the flexible printed circuit board 10 has a body portion 11 extending in a first direction and a plurality of branch portions 20 each branching from the body portion 11 and arranged intermittently in the first direction, the plurality of branches 20 has a connection terminal 55 connected to a cell terminal 220, which is a terminal of the battery cell 210, at a tip side thereof, and among the plurality of branches 20, the branch 20 located farther from a reference position 510 in the first direction has a larger length dimension of the branch 20 from a base end of the branch 20 to the connection terminal 55.SELECTED DRAWING: Figure 4 【課題】バッテリセルの収縮又は膨張に伴うセル端子の移動量が大きい場合であっても、接続端子が当該セル端子の移動に良好に追従することが可能な構造の電圧監視モジュールを提供する。【解決手段】本実施形態に係る電圧監視モジュール１００は、複数の配線５１を有するフレキシブルプリント基板１０を備え、フレキシブルプリント基板１０は、第１方向に延在する本体部１１と、それぞれ本体部１１から分岐し、第１方向において間欠的に配置されている複数の分岐部２０と、を備え、分岐部２０は、その先端側の部位に、バッテリセル２１０の端子であるセル端子２２０に接続される接続端子５５を有し、複数の分岐部２０のうち、第１方向において基準位置５１０からより遠くに位置する分岐部２０の方が、当該分岐部２０の基端から接続端子５５までの当該分岐部２０の長さ寸法が大きい。【選択図】図４
