A carbon nanotube fiber having both excellent electrical conductivity and mechanical properties and a method for producing the same are provided. A long carbon nanotube fiber 11 formed by aggregating a plurality of carbon nanotubes 12 has a diameter in the range of 0.4 to 100 nm, and the carbon nanotube fiber 11 has an axial direction of the carbon nanotube fiber 11. And oriented at an angle in the range of 0 to 5 °. [Selection] Figure 1 |
