A flexible flat cable includes a plurality of conductors arranged in parallel at predetermined intervals, an insulation layer provided on both surfaces of the conductors, a nonwoven fabric layer provided on an outer surface of the insulation layer, and a shield layer provided on an outer surface of the nonwoven fabric layer. The nonwoven fabric layer includes a nonwoven fabric having a plurality of recessed portions formed on a surface thereof, the recessed portion being enclosed by a pair of opposite long sides and a pair of opposite short sides.

Flexible flat cable

A flexible flat cable includes a plurality of conductors arranged parallel at predetermined intervals, an insulation layer covering both sides of each of the plurality of conductors, a nonwoven fabric layer on an outer surface of the insulation layer, and a shield layer on an outer surface of the nonwoven fabric layer. The nonwoven fabric layer includes a nonwoven fabric including a layer including a first fiber thread with a predetermined outer diameter and a second fiber thread with an outer diameter larger than that of the first fiber thread. A basis weight of the nonwoven fabric is 50 to 90 g/m.

A differential signal transmission cable has four stranded cores, each formed of an inner conductor covered with an insulation of fluorocarbon resin; an outer conductor being spirally wrapped around the four stranded cores in the opposite direction to a stranding direction of the cores; and a sheath formed around the outer conductor, where the diameter of the cable is 1.0 mm or less.

Differential signal transmission cable

A metal-shielded cable includes a core made of insulated wires each having a conductor coated with an insulation layer. The core is surrounded with a composite metal shield which includes a laminated metal-plastic layer and a shield layer. The shield layer includes a tape formed of woven filaments, which is wound around or aligned longitudinally along the core of the cable.
