A carbon nanotube composite includes a carbon nanotube bundle including a plurality of carbon nanotubes that are bundled, each of the plurality of carbon nanotubes having a single-walled or multi-walled structure, and a group of elements of other type introduced in an aligned manner into a gap portion between the plurality of carbon nanotubes. In the carbon nanotube bundle, a ratio of the number of carbon nanotubes having a double-walled or triple-walled structure to the number of the plurality of carbon nanotubes is greater than or equal to 50%, and other-type element bonded bodies constituting the group of elements of other type are arranged in line along a longitudinal direction of the carbon nanotubes.

A low-resistivity carbon nanotube aggregate includes a plurality of carbon nanotubes each having one or more walls, wherein a ratio of a total number of carbon nanotubes that have two or three walls relative to a total number of said plurality of carbon nanotubes is 75% or greater, and wherein, in a G band of a Raman spectrum in the Raman spectroscopy of the plurality of carbon nanotubes, a G+/Gtotal ratio that is indicative of an amount of semiconductor carbon nanotubes relative to metallic carbon nanotubes is 0.70 or greater.
