PROBLEM TO BE SOLVED: To restrain an electromagnetic wave from entering a signal line wired in an FPC connecting a first circuit wiring board and a second circuit wiring board. SOLUTION: Plural signal lines 51 and plural earth wires 52 are laid in parallel in the FPC 50, and the earth wires 52 are laid at least on one side of both adjacent sides of the signal line 51. Thus, the earth wire 52 for absorbing electromagnetic waves are arranged next to the signal lines 51, whereby electromagnetic waves can be restrained from entering the signal lines 51 so as to prevent erroneous operation of display means 11 to 15 due to erroneous operation of both circuit wiring boards 30, 40.
