To provide a cable routing structure of a flexible flat cable which inhibits induction of noise into the flexible flat cable and reduces unnecessary radiant noise.

An electronic appliance includes first and second members which can be engaged with/disengaged from each other, a first circuit board 60 to be mounted on the first member, a second circuit board 70 to be mounted on the second member, and the flexible flat cable 80 for electrically connecting the first board 60 with the second board 70. At least one of the first and second boards 60 and 70 has a circuit region 68 for handling a high frequency signal. The flexible flat cable 80 is routed as folded a plurality of times not to overlap the circuit region 68 for handling the high frequency signal.
