A cable arranging structure for exchanging electric signals between a pair of printed circuit boards includes at least a pair of electrically conductive members adapted to arrange the cable between them over the entire length thereof. The electrically conductive members show an electric potential substantially equal to that of the ground. Such a structure requires only the two electrically conductive members to be rigidly secured so that radiant noises generated by the cable can be effectively suppressed by means of the structure without the need of deforming the cable.
