| 1. A method for producing a carbon nanotube thin film comprising:
a step of dropping a mixed liquid containing carbon nanotubes and an ionic liquid onto a liquid surface of a film forming
liquid to spread the carbon nanotubes on the liquid surface;
wherein the carbon nanotubes are dispersed in the ionic liquid, and
the carbon nanotubes have a functional group selected from the group consisting of: —COOH, —OH, —CHO, —COOR and —SiR3 wherein R represents a hydrocarbon group.
