摘要： A production method of a carbon nanotube yarn includes the steps of: (1) obtaining a web 40 including a large number of carbon nanotubes 36; (2) bringing a slider 24a into contact with the carbon nanotubes 36; and (3) moving the slider 24a in a direction to bundle the carbon nanotubes 36, the direction being inclined with respect to a direction in which the web 40 extends.

摘要： A production method of a long member including a large number of carbon nanotubes includes the steps of: (1) drawing the carbon nanotubes gradually from a first array to obtain a first web 10a; (2) bringing the first web 10a partially into contact with a first holder 12a to hold the first web 10a on the first holder 12a; (3) drawing the carbon nanotubes gradually from a second array to obtain a second web 10b; (4) bringing the second web 10b partially into contact with a second holder 12b to hold the second web 10b on the second holder 12b; and (5) placing a portion of the first web 10a and a portion of the second web 10b on each other to form a joint, the portions of the first and second webs 10a and 10b being in the vicinity of the first and second holders 12a and 12b, respectively, and being placed on each other such that width directions of the first and second webs 10a and 10b are substantially the same.

摘要： A plurality of CNTs 10 are drawn out of VACNTs 2 so as to be continuous in lines and are bundled into a thread shape, and a temporary thread 11 bundled into a thread shape is temporarily wound on the first winder 12. The first winder 12 is then rotated about an axis along a feeding direction of the temporary thread 11 to twist the temporary thread 11 while the temporary thread 11 is fed from the first winder 12.
