Zusammenfassung:Provided is a carbon nanotube aggregate by which it is possible to realize further reduction in resistance compared to conventional carbon nanotube wires, as well as realizing comparable resistivity to copper and aluminum, and major improvement in electrical properties. A CNT aggregate (1) is constituted of a plurality of CNT bundles (11) having a structure with one or more walls. The CNT bundles 11 are bundles having a plurality of CNTs (11a). In the CNT aggregate (11), the ratio of the total number of CNTs having a two- or three-walled structure in relation to the number of CNTs (11a) is 75% or greater, and among peaks due to a G band of a Raman spectrum in Raman spectroscopy, a G+/Gtotal ratio due to semiconductor CNTs is 0.70 or greater.
