BATTERY WIRING MODULE

WIPO Patent Application WO/2021/095388

A1

Provided is a battery wiring module having a novel structure capable of improving the degree of freedom in wiring a voltage detection line configured by a printed wiring of a flexible printed board without causing a short circuiting problem.　The battery wiring module 14 comprises: a plurality of connection members 18, 20 connected to an electrode terminal 16; and a flexible printed board 24 having a plurality of voltage detection lines 30, 34 for detecting the voltages of a plurality of power storage elements 12 via the plurality of connection members 18, 20, wherein at least one among the plurality of voltage detection lines 30, 34 includes a front surface wiring 30 formed on a front surface 26 of the flexible printed board 24, a rear surface wiring 34 formed on a rear surface 28 of the flexible printed board 24, and a front and rear conduction unit 32 that penetrates the flexible printed board 24 in a plate thickness direction to connect the front surface wiring 30 and the rear surface wiring 34, and the resistance value per unit length of the front and rear conduction unit 32 is equal to or less than the maximum resistance value per unit length of the front surface wiring 30 and the rear surface wiring 34.
