PROBLEM TO BE SOLVED: To provide a flexible printed wiring board capable of transmitting a high-frequency signal at high speed. SOLUTION: This flexible printed wiring board includes: an insulating sheet 5; a plurality of lines of conductors 1 and 2 provided on the insulating sheet 5; and conductive sheets 6 which cover outer peripheries of the conductors 1 acting as signal lines out of the plurality of lines of conductors 1 and 2 with spaces A; and is characterized in that the conductive sheets 6 are respectively provided on both sides of the insulating sheet 5 and electrically connected to the conductors 2 acting as ground lines out of the plurality of lines of conductors 1 and 2, and conductive connection parts 11 each having a structure having slits 7 formed at predetermined intervals along the longitudinal direction of the conductors, and arranged on the conductive sheet 6 are formed on the conductive sheet 6 to be extended between the slits 7.
