There is provided a flexible wiring member capable of electrically connecting desired points separated in a length direction. The flexible wiring member includes conductor holding layers that are formed in a state of being stacked in a thickness direction and being electrically insulated from one another; power supply line conductors that have a wide width and are respectively disposed in both of a first conductor holding layer and a second conductor holding layer adjacent to each other in the thickness direction; and communication line conductors that have a width smaller than that of the power supply line conductors and are disposed in one of the first conductor holding layer and the second conductor holding layer, in which the conductor holding layers are formed by an insulating resin, and directly cover the power supply line conductors and the communication line conductors.
