PROBLEM TO BE SOLVED: To provide a method for producing a yarn comprising a polymer nanofiber by which the yarn comprising the polymer nanofiber, and having a strength higher than that produced by a conventional method for producing the yarn comprising the polymer nanofiber can be produced.SOLUTION: The method for producing the yarn comprising the polymer nanofiber includes a first step of producing a belt-shaped nonwoven fabric comprising the polymer nanofiber 12 to the surface of which a nano structure (preferably multilayered carbon nanotube) is attached, and a second step of producing the yarn comprising the polymer nanofiber from the belt-shaped nonwoven fabric by passing the belt-shaped nonwoven fabric through a yarn-twisting apparatus, in this order. |
