PROBLEM TO BE SOLVED: To provide a flexible printed wiring board where the circuit of high density can precisely be connected to the conductor of an opposite side. SOLUTION: In the flexible printed wiring board, conductor circuits 5 coated with an insulating coating resin layer 1 and connection terminals 4 where conductors are exposed are installed on one face or both faces of an insulating resin layer. One or more slits 3 are made between the conductor circuits coated with the insulating coating resin layer 1.
