Abstract: A carbon nanotube aggregate includes a plurality of carbon nanotubes, a metal compound, and an oxide of the metal compound. The metal compound is contained in a space inside of each of the carbon nanotubes and/or in a space defined between the plurality of carbon nanotubes. When the metal compound is added inside the carbon nanotube aggregate, the metal compound is oxidized by reacting with oxygen or the like during or after a production process of the CNT aggregate, and the oxide is formed in the opening of the space to which the metal compound is added, so that the metal compound is capped with the oxide. Since the metal compound inside the CNT aggregate is shielded from the atmosphere, separation of the metal compound and reaction between the metal compound and oxygen and water in the atmosphere are suppressed, increasing heat resistance of the carbon nanotube aggregate.

Abstract: A carbon nanotube aggregate includes a plurality of carbon nanotubes, a metal compound added to inside and/or outside of each of the carbon nanotubes, and an oxide film that is made of an oxide of the metal compound, and covers an outer periphery of the plurality of carbon nanotubes to define an outer surface of the carbon nanotube aggregate. Since the metal compound is shielded from the atmosphere by the oxide film, separation of the metal compound and reaction of the metal compound with oxygen or water in the atmosphere are suppressed, increasing heat resistance of the carbon nanotube aggregate.

Abstract: A conducting wire includes a conducting wire element. The conducting wire element includes a conductor made of carbon as a main component and extending along a longitudinal direction and an insulator connected to the conductor and extending along a longitudinal direction. The insulator includes a core made of a material that is more plastically deformable than the conductor and a first adhesive made of an insulating material, disposed on the core, and joined to one side of the conductor.
