Claim of US Patent No. 9,883,581

11. A multi-core differential signal transmission cable, comprising:
a plurality of differential signal cables, each of the differential signal cables comprising:
a pair of signal line conductors for transmitting differential signals;
an insulation collectively covering the pair of signal line conductors;
a shielding tape wrapped around the insulation; and
an insulating tape wound around the shielding tape,
wherein a gap is formed between an outer peripheral surface of the insulation and an inner surface of the shielding tape such
that the insulation is movable relative to the shielding tape; and

a cylindrical interposed material confining a pair of the plurality of the differential signal cables at a center of multi-core
differential signal transmission cable,

wherein the cylindrical interposed material is in a contact with opposing edges of at least one of the pair of the plurality
of the differential signal cables,

wherein the cylindrical interposed material abuts all of the plurality of the differential signal cables.
