To realize reduction in size of an electronic device by making smaller the space where the intermediate portion of a flexible printed circuit board is allocated in an electronic device, in which at least two portions are coupled via a hinge mechanism and the circuits provided individually to these two portions are connected via the flexible printed circuit board.

In this electronic device 1, at least two portions 2, 3 are coupled via the hinge mechanism 4 and the circuit portions 29, 30 individually provided to these two portions are connected via the flexible printed circuit board 31, the flexible printed circuit board is turned once in the space provided adjacently in the axial direction of the hinge mechanism, and at least a part of the portion which is once turned of the flexible printed circuit board is turned around a part 20 of the hinge mechanism.
