PROBLEM TO BE SOLVED: To provide a carbon nanotube device having high directivity of a carbon nanotube, for example, a large amount of electron emission when used as an electron-emitting device. Kind Code: A1 A carbon nanotube device comprising a substrate having a conductive surface and a carbon nanotube having one end bonded to the conductive surface so as to be able to conduct, the bonding portion of the carbon nanotube to the conductive surface. Is a carbon nanotube device surrounded by a barrier. |
