Abstract: The present invention provides a method for producing a carbon nanotube sheet that is excellent in light transmittance and conductivity, and the carbon nanotube sheet. The method includes firstly modifying of modifying a free-standing unmodified carbon nanotube sheet in which a plurality of carbon nanotubes are aligned in a predetermined direction. The firstly modifying includes performing a densification process of bringing the unmodified carbon nanotube sheet into contact with either one of or both of vapor and liquid particles of a liquid substance to produce a modified carbon nanotube sheet that contains the carbon nanotubes which are mainly aligned in a predetermined direction, and that includes a high density portion where the carbon nanotubes are assembled together and a low density portion where density of the carbon nanotubes is relatively lower than density in the high density portion.

Abstract: It is an object of the present invention to provide a carbon nanotube forest laminated body that enables easy production of a carbon nanotube sheet from a carbon nanotube forest and a method of producing a carbon nanotube forest laminated body. The carbon nanotube forest laminated body of the present invention includes a support having an adhesive (sticky) surface and a carbon nanotube forest provided on the surface of the support. The surface of the support has an adhesive strength of 0.01 N/25 mm or more and 2 N/25 mm or less, and the carbon nanotube forest is provided on the surface.
