Abstract

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.
