Abstract: The present disclosure relates to a carbon nanotube strand wire capable of realizing further weight reduction as compared with a wire configured of a core wire made mainly of metal such as copper or aluminum and achieving both satisfactory durability in bending and handling ability. A CNT strand wire is obtained by twisting a plurality of CNT wires of a plurality of bundled CNT aggregates configured of a plurality of CNTs together. At least a number of twists t1 of the CNT wires and a number of twists t2 of the CNT strand wire is equal to or greater than 1000 T/m.

Abstract: There is provided a CNTs wire capable of materializing a low resistivity and improving the electroconductivity. The CNT wire is formed from a single CNT aggregate constituted of a plurality of CNTs . . . having a single- or multi-walled structure, or formed by bundling a plurality of the CNT aggregates. The proportion of the total number of the CNTs having a double-walled or triple-walled structure based on the number of the plurality of CNTs constituting the CNT wire is 75% or higher; the proportion of the total number of the CNTs having an average diameter of the innermost wall of 1.7 nm or smaller based on the number of the CNTs constituting the CNT wire is 75% or higher; and the full-width at half maximum Δθ in azimuth angle in azimuth intensity distribution by SAXS indicating orientation of the plurality of CNT aggregates is 60° or smaller.
