Abstract
A process for producing aligned carbon nanotube films, wherein a carbon compound is decomposed using a substrate that is coated with an element having no catalytic ability by itself and which loads a metallic element having catalytic ability or a compound thereof, thereby forming a film of fine carbon nanotubes on the surface of the substrate which are aligned in a direction perpendicular to the substrate.
