In order to obtain a carbon nanotube array including no m-CNTs through simple steps using a mechanism that is different from thermocapillary flow, there are provided a process for producing a carbon nanotube array including (A) a step of preparing a carbon nanotube array in which m-CNTs and s-CNTs are horizontally aligned; (B) a step of forming an organic layer on the carbon nanotube array; (C) a step of applying voltage to the carbon nanotube array in a long axis direction of the carbon nanotubes constituting the carbon nanotube array in the air; and (D) a step of removing the organic layer, and a carbon nanotube array obtained by the process.

The present invention provides: a film that comprises single-layer carbon nanotubes having shapes which enable the characteristics thereof to be sufficiently exhibited; and a process for producing the film. The film, which comprises single-layer carbon nanotubes, has portions where single-layer carbon nanotubes are densely present and portions where single-layer carbon nanotubes are sparsely present, the dense portions forming a pseudo-honeycomb structure in a surface of the film.
