Abstract
A first electrical connector 30 and a second electrical connector 40 are installed on opposed ends of a two-sided flexible printed circuit 50, and the connectors are connected by two layers of conductive patterns. In the intermediate parts 22a and 22b, the conductors 20a of the upper-side circuit pattern and the conductors 20b of the lower-side circuit pattern are arranged so that they extend substantially parallel to each other and are shifted in a pitch direction. Accordingly, electrical connections can be realized in which crosstalk is prevented while a relatively high impedance is maintained; furthermore, the resistance of the FPC 50 to bending is also strengthened.
