Abstract
A method for manufacturing a twisted carbon nanotube yarn includes: drawing carbon nanotubes in sheet form from an end portion of a carbon nanotube forest to provide a carbon nanotube sheet; performing false twisting by twisting the carbon nanotube sheet and then performing untwisting to provide a carbon nanotube linear body; and twisting the carbon nanotube linear body to provide a twisted carbon nanotube yarn, in which the number of twists when the carbon nanotube sheet is false-twisted in the false twisting is in a range from 300 T/m to 5,000 T/m, and the number of twists when the carbon nanotube linear body is twisted in the providing of the twisted carbon nanotube yarn is in a range from 900 T/m to 5,000 T/m.
