8. A method for producing a carbon nanotube sheet, which comprises:
-
immersing an aligned carbon nanotube base material including a substrate, and the group of carbon nanotubes in which a plurality of carbon nanotubes are vertically aligned in the form of a bundle to the substrate, in an amphiphilic molecule-containing solution; drying the immersed aligned carhop nanotube base material; impregnating the dried aligned carbon nanotube base material with a monomer; polymerizing the monomer thereby to form a carbon nanotube sheet, in which the space between carbon nanotubes is filled with the polymer, on the substrate; and peeling the carbon nanotube sheet from the substrate. - View Dependent Claims (10, 11)

9. A method for producing a carbon nanotube sheet, which comprises:
-
immersing an aligned carbon, nanotube base material including a substrate, and the group of carbon nanotubes in which a plurality of carbon nanotubes are vertically aligned in the form of a bundle to the substrate, in an amphiphilic molecule-containing solution; washing the aligned carbon nanotube base material with a washing solvent; impregnating the aligned carbon nanotube base material, which is made to be present in a vertically downward state, with a monomer; polymerizing the monomer thereby to form a carbon nanotube sheet on the substrate; and peeling the carbon nanotube sheet from the substrate;
whereinthe aligned carbon nanotube base material is prevented from drying in a range from immersion in the amphiphilic molecule-containing solution to impregnation with the monomer.
