Proposed is a reduction of variance in electromagnetic noise eliminating effect with signal conductors arranged in a flat cable to which an electromagnetic noise absorber is attached. The electromagnetic noise absorber is provided with a plate magnetic body and a U-shaped magnetic body. Since the width of the plate magnetic body is smaller than the interval between the side walls of the U-shaped magnetic body, the plate magnetic body can be accommodated in the U-shaped magnetic body, with a clearance formed between the end portions of the plate magnetic body and the side walls of the U-shaped magnetic body. The impedance in the vicinity of the clearance is decreased, and the difference in impedance between the end portions and the middle portion of the electromagnetic noise absorber is decreased. Therefore, a variance in the electromagnetic noise eliminating effect with signal conductors of the flat cable is made small.
