(57) Abstract: The present invention provides a method for producing an oriented carbon nanotube film composed of a large number of oriented carbon nanotubes. A carbon compound is decomposed by using a substrate coated with an element having no catalytic action by itself and carrying another metal element having a catalytic action or a compound thereof, thereby forming the substrate on the substrate surface. A method for producing an oriented carbon nanotube film, characterized by forming a carbon nanotube film oriented in a vertical direction. An oriented carbon nanotube film having a small outer diameter is obtained. |
