Abstract
An amorphous carbon layer sticking on a carbon nanotube surface is remarkably reduced when a carbon nanotube is joined to a conductive substrate by bringing a single fibrous carbonaceous material in contact with the tip of the conductive substrate and covering at least a part of the contact portion with a conductive material while at lest either of the fibrous carbonaceous material or the conductive substrate is heated in a vacuum.
