摘要： A carbon nanotube composite material (1) includes a metal base material (10) and carbon nanotube electrically-conductive path portions (20). The metal base material (10) is made from a polycrystalline substance in which a plurality of rod-shaped metal crystal grains (11) are oriented in a direction. The carbon nanotube electrically-conductive path portions (20) are made from doped carbon nanotubes having a dopant, existing in parts of grain boundaries (15) between the rod-shaped metal crystal grains (11) in a cross section of the metal base material (10), and forming an electrically-conductive path which is electrically conductive in a longitudinal direction of the metal base material (10), by existing along the longitudinal direction (L).

摘要： Provided is a carbon nanotube composite wire including: a substrate; a carbon nanotube; and a thin metal film formed on the carbon nanotubes, wherein the carbon nanotube has a peak ratio (G/D) of a G band to a D band in a Raman spectrum of 5 or more and 30 or less, a carbon nanotube occupied area ratio that is a ratio of a cross-sectional area of the carbon nanotube to a sum of the cross-sectional area of the carbon nanotube and a cross-sectional area of the thin metal film is 10% or less in the cross section perpendicular to the longitudinal direction, and an amorphous layer made from a metal oxide is present at an interface between the carbon nanotube and the thin metal film, and a thickness of the amorphous layer is within a range of 1 nm or more and 5 nm or less.
