1. An antenna cable noise suppression structure, comprising:
a plurality of antenna cables; and
a noise suppression member having electrical conductivity and being electrically connected to each of outer conductors of the plurality of antenna cables, wherein
the noise suppression member is wound around the plurality of antenna cables and has a length (L1) extending along a cable axis direction from an end portion of each antenna cable to a contact position at which the noise suppression member is electrically connected to an outer conductor of each antenna cable,
wherein the length (L1) is equal to or less than one quarter of a wavelength calculated based on a frequency of a signal transmitted by each antenna cable, and
the noise suppression member and the outer conductor of each antenna cable that is electrically connected to the noise suppression member are grounded to a grounded portion.
