PROBLEM TO BE SOLVED: To provide a cable noise suppression device for an airborne electronic equipment which can suppress a radiating noise from a cable between a three- phase AC generator and a switching shunt power circuit, to which power is supplied from the generator, to a required level. SOLUTION: This device includes a three-phase power cable 3 for connecting a three-phase AC generator 1 for airborne electronic equipment and a switching shunt power circuit 2 to which power is supplied from the generator, a conductive inner shield 4 covering the cable, a doughnut ferrite core 6 surrounding a part of the internal shield, and a ferromagnetic outer shield 8 covering the inner shield and the ferrite core. Both the inner shield 4 and the outer shield 8 are grounded.
