Carbon nanotube dispersion liquid and method of producing same

A carbon nanotube dispersion liquid comprising:

• a plurality of carbon nanotubes;
• a solvent;
• and a thickener, wherein
• the plurality of carbon nanotubes include single-walled carbon nanotubes,
• at least some of the plurality of carbon nanotubes form carbon nanotube bundles, and
• upon observation of the carbon nanotube bundles using a scanning electron microscope, an average length of the carbon nanotube bundles is more than 1.50 μm, an average diameter of the carbon nanotube bundles is 16.0 nm or less, and a number of bundles having a diameter of more than 30.0 nm among 100 of the carbon nanotube bundles is 15 or less.
