A conductive member module includes a flat cable that includes a plurality of conductors and an insulating coating covering the conductors, a distal end part of each of the conductors being exposed from the coating, and a plurality of conductive members each of which includes a plate-shaped main body and a conductor holding part, the main body being connected to a portion of each of the conductors exposed from the coating by welding, the conductor holding part being separated from the main body at other sides except for one side connected to the main body by cutting in the main body and being folded back toward the main body to hold a portion of each conductor closer to a base end side than a part welded to the main body, the conductive members being continuously arranged along an extending direction of the flat cable.
