Abstract

A battery wiring module is to be combined with a battery module including a plurality of battery cells stacked in a state of being alternatively reversed so that a positive electrode terminal and a negative electrode terminal are adjoined between the adjacent battery cells. The battery wiring module is provided with a plurality of linear conductors which are arranged in parallel at an interval, a plurality of bus bars which are arranged at a predetermined interval along to at least one side of the plurality of linear conductors, and an insulation resin part which integrally covers both an outer periphery of the plurality of linear conductors and side edges of the plurality of bus bars adjacent to the linear conductors.
