PROBLEM TO BE SOLVED: To provide a new flexible printed circuit board which is hardly reduced in durability even when it is repeatedly rotated while a flexible interconnect line member is wound thereon in spirals, easily assembled together, and more increased in the number of interconnect lines than a single-sided board. SOLUTION: A pair of rectilinear flexible interconnect line members 101 and 102 which can be folded in half along a folding line VL provided at a one lengthwise end and overlap with each other when they are folded in half, a first and a third connectors 11 and 13, which are extended in the direction so as to cross the lengthwise direction from the ends of the interconnect line members 101 and 102 on the folding line VL side, and a second and a fourth connectors 12 and 14, which are extended in the opposite direction from the other ends of the interconnect lines 101 and 102, are integrally formed with a sheet of base film, and conductor interconnect lines 16a and 16b and terminals 15a to 15d are formed in the flexible printed circuit board 1.
