Abstract: Provided is a method for efficiently producing a carbon nanotube (CNT) dispersion liquid of highly dispersed CNTs while also suppressing damage to the CNTs. The method for producing a carbon nanotube dispersion liquid includes a dispersing step that includes at least one cycle of dispersing treatment in which pressure is applied to a coarse dispersion liquid containing carbon nanotubes and a dispersion medium, the coarse dispersion liquid is fed under pressure, and shear force is applied to the coarse dispersion liquid such as to disperse the carbon nanotubes. A plurality of repetitions of the dispersing step are performed while altering the pressure that is applied to the coarse dispersion liquid. In at least one instance, the pressure applied to the coarse dispersion liquid is altered by at least 10 MPa between consecutive repetitions of the dispersing step.
