To provide a shieldless paired cable having excellent easiness to be handled at the time of wiring and excellent transmitting property and crosstalk attenuation property.
This shieldless paired type cable 7 is manufactured by producing paired and twisted wires 4 by pairing and twisting electric wires 3 of a conductor 1 coated with an insulator 2 at prescribed pitches, producing unit 5 by twisting a plurality of the paired and twisted wires 4, bundling a plurality of the units 5a, and at the same time collectively coating their circumference with a sheath 6. The 2%-modulus value of the insulator 2 is at least within 0.5-2.5kgf/mm2 and near end crosstalk attenuation NEXT in a frequency range (f) from 1 to 100MHz satisfies the following relation: NEXT (f) ≥64-15log(f/0.772) in all of the pairs.
