The invention provides a textile thread composed of carbon nanotubes and a method for manufacturing the same. The method for manufacturing a textile thread comprising carbon nanotubes comprises: a step for manufacturing a textile thread precursor [alpha] by drawing out a plurality of carbon nanotubes from a carbon nanotube forest and spinning the plurality of carbon nanotubes while applying a tension of 6 mN or less per 1 cm width of the carbon nanotube forest to the plurality of carbon nanotubes to obtain a textile thread precursor [alpha]; thereby producing a spinning thread precursor alpha; a spinning yarn precursor [beta] manufacturing step for applying a higher tension than the tension in the spinning yarn precursor [alpha] manufacturing step to the spinning yarn precursor [alpha], thereby manufacturing a spinning yarn precursor [beta] in which the spinning yarn precursor [alpha] is densified; and a spun yarn manufacturing step for manufacturing a spun yarn by applying tension to the spun yarn precursor
