PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube thin film, by which a uniform carbon nanotube thin film can be easily produced regardless of whether each carbon nanotube to be used has a functional group or not; and a method for producing a carbon nanotube thin film, by which the carbon nanotube thin film can be directly formed on the surface of an arbitrary substrate. SOLUTION: The method for producing the carbon nanotube thin film includes a dropping process for dropping a mixed liquid containing carbon nanotubes 2 and an ionic liquid on the liquid surface of a film-forming liquid 4 and spreading the carbon nanotubes 2 on the liquid surface. Preferably, the method for producing the carbon nanotube thin film includes a compressing process for compressing the thin film of the carbon nanotubes 2 spread on the liquid surface in the direction (indicated by the arrow A) parallel to the liquid surface and/or a pulling process for pulling the thin film of the carbon nanotubes 2 spread/compressed on the liquid surface of the film-forming liquid 4.
