WIRING MODULE

The purpose of the present invention is to provide a wiring module in which both a grommet and a planar member are provided to a wiring member, wherein the assemblability into a door panel can be improved. The wiring module comprises: a wiring member; a planar member that holds the wiring member; and a grommet that is attached more toward a vehicle body side than the portion of the wiring member that is held by the planar member. The planar member includes: a main plate part that holds a section of the wiring member which extends along an inner plate part of a door panel; and a planar member-side attachment part that is attached to the grommet. The grommet includes: a base part that is fixed at a fixed position to the door panel; and a grommet-side attachment part to which the planar member-side attachment part is attached.
