PROBLEM TO BE SOLVED: To provide a flexible printed circuit board that is manufactured at low cost and enhanced in bending resistance characteristics (slide resistance characteristics). SOLUTION: A flat wiring portion S2 is formed to be freely bent on the whole. Slits (cutting lines) 27 which extend in a length direction L are formed at positions where the flexible printed circuit board 20 is divided into, for example, three in a width direction W. With the slits 27, the flat wiring portion S2 has a plurality of divided wiring portions S21, S22 and S23 each divided into a prescribed number of conductive layers 22, among many conductive layers 22. Further, the flat wiring portion S2 comprises: an inclined wiring portion D1 extending having its width direction w1 inclined at a prescribed angleθ1 to a width direction w2 of connector portions S1; and twist portions D2 connecting the inclined wiring portion D1 and connector portions S1 at both ends of the inclined wiring portion D1.
