To realize wiring of voltage detection purpose electric wires for a battery pack in a battery pack busbar module without requiring the complicated work of setting a different voltage detection terminal than the busbar in a busbar housing section.
A busbar module 1 includes a plurality of busbars 10 having a hole 12 formed therein and a plurality of busbar housing sections 20 respectively supporting and enclosing each of the busbars 10, some of the busbars 10 being provided with an electric wire connecting part 13 formed integrally with a terminal part 11 and having a groove 14 formed therein, into which is fitted an end of an electric wire 60. A core wire 62 of the electric wire 60 is welded inside the groove 14 by resistance welding. A support part 22 of the busbar housing section 20 is formed protrusively from an enclosing part 21 to the inside at a non-interfering position on the back of the groove 14 of the busbar 10, thus supporting only an edge of the terminal part 11 of the busbar 10.
