摘要： The present invention relates to a carbon nanotube strand wire capable of realizing electroconductivity that is equivalent to electroconductivity of a wire configured of a core wire made mainly of metal such as copper or aluminum, realizing excellent handling ability, and additionally realizing further weight reduction. A CNT strand wire (1) is obtained by twisting a plurality of CNT wires (10) of a plurality of bundled CNT aggregates (11) configured of a plurality of CNTs (11a) together. At least one of a number of twists t1 of the CNT wires (10) and a number of twists t2 of the CNT strand wire (2) is equal to or greater than 2500 T/m, or the number of twists t1 of the CNT wires (10) is equal to or greater than 1000 T/m and less than 2500 T/m while the number of twists t2 of the CNT strand wire (2) is equal to or greater than 500 T/m and less than 2500 T/m, or the number of twists t1 of the CNT wires (10) is equal to or greater than 500 T/m and less than 1000 T/m while the number of twists t2 of the CNT strand wire (2) is equal to or greater than 1000 T/m and less than 2500 T/m.

摘要： The present invention relates to a carbon nanotube strand wire capable of realizing electroconductivity that is equivalent to or higher than electroconductivity of a wire configured of a core wire made mainly of metal such as copper or aluminum, realizing excellent bendability, and also realizing further weight reduction. The carbon nanotube strand wire (2) is obtained by twisting a plurality of CNT wires (10) of a plurality of bundled CNT aggregates (11) configured of a plurality of CNTs (11a) together. A number of twists t1 of the CNT wires (10) is equal to or greater than 0 and less than 2500 T/m, and a number of twists t2 of the CNT strand wire (2) is greater than 0 and less than 2500 T/m.

摘要： There is provided a CNT wire capable of materializing a low resistivity and improving the electroconductivity. The CNT wire (1) is formed from a single CNT aggregate (11) constituted of a plurality of CNTs (11a), (11a) ··· having a single- or multi-walled structure, or formed by bundling a plurality of the CNT aggregates (11). 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 (11a), (11a) ··· constituting the CNT wire (1) 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 (1) 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 (11), (11) ··· is 60° or smaller.
