Abstract: Provided is an aqueous carbon nanotube dispersion with excellent dispersibility of carbon nanotubes in water. An aqueous carbon nanotube dispersion containing carbon nanotubes dispersed in water, wherein the carbon nanotubes have a mean particle diameter (D50) of 1 μm or less, and when the carbon nanotubes are prepared as an aqueous dispersion with a concentration of 0.1% by mass, a spin-spin relaxation time (T22) of a second component is 1000 msec or less as measured by a measurement method as set forth below:

The spin-spin relaxation time (T22) of the second component is calculated by fitting a relaxation curve measured at 30° C. using an H nuclear CPMG pulse sequence method to a curve represented by expression (1):
