A wiring member includes a sheet material and a wire-like transmission member extending in a plane direction of the sheet material and fixed to the sheet material by a contact area direct fixation at intervals in three or more positions in a longitudinal direction of the wire-like transmission member. When an interval between two contact area direct fixation positions continuous in a longitudinal direction of the wire-like transmission member in contact area direct fixation positions of the sheet material and the wire-like transmission member is a fixation interval, the wiring member includes portions that differ in the fixation interval.
