Abstract:
1. A bus bar module comprising: a plurality of bus bars each of which connects adjacent positive electrode and negative electrode of a plurality of batteries to each other so as to connect the plurality of batteries in series, the plurality of batteries being arranged so that the positive electrodes and the negative electrodes are alternately arranged; a plurality of voltage detection terminals that are respectively connected to the bus bars; a plurality of electric wires that are respectively connected to the voltage detection terminals; and an insulating plate on which a fixing section adapted to fix the bus bars and a wiring path adapted to accommodate the electric wires are formed, wherein the insulating plate includes a drawing section for the electric wires which is formed so that a bottom plate and a side wall of the wiring path are extended and projected from the insulating plate, and a tongue piece which is projected from a tip portion of a bottom plate of the drawing section; wherein a winding member is wound around the tongue piece and the plurality of electric wires so as to bundle the electric wires together on the tongue piece to fix the electric wires to the tongue piece; wherein the tongue piece is bent in a direction opposite to a rising direction of a side wall of the drawing section wherein an end portion of the side wall is projected further than the tip portion of the bottom plate of the drawing section where the tongue piece is projected, in an extending direction of the electric wires around which the winding member is wound; wherein the side wall includes a pair of sidewalls which face each other; and wherein the pair of sidewalls extend from the bottom plate of the drawing section in a direction perpendicular to the bottom plate of the drawing section.
