A carbon nanotube dispersion comprising:
- a dispersion medium;
- and
- a nanocarbon material containing carbon nanotubes dispersed in the dispersion medium, wherein
- 98% or more of the nanocarbon material has a length of 1 μm or more and 105 μm or less and the nanocarbon material has an average aspect ratio of 100 or more and 20000 or less.

A method for producing a carbon nanotube dispersion, comprising:
- performing a first dispersion treatment on a nanocarbon material containing an aggregates of carbon nanotubes to adjust a length of 95% or more of the nanocarbon material to 1 μm or more and 105 μm or less;
- and
- performing a second dispersion treatment on the nanocarbon material after the first dispersion treatment to loosen at least a part of the aggregates, wherein
- 98% or more of the obtained nanocarbon material has a length of 1 μm or more and 105 μm or less and the obtained nanocarbon material has an average aspect ratio of 100 or more and 20000 or less.
