The method for producing a semiconductor-type SWCNT dispersion of the present invention is to prepare a SWCNT dispersion to be separated containing a polymer containing the SWCNT mixture, an aqueous medium, and a structural unit A derived from a monomer represented by the following formula (1). Step A and Step B of collecting the supernatant containing the semiconductor type SWCNT from the centrifuged SWCNT dispersion after centrifuging the SWCNT dispersion to be separated. The weight average molecular weight of the polymer is 1,000 or more and 100,000 or less. |
