An ultraconductor includes: a base substrate; a carbon nanotube layer on the base substrate, the carbon nanotube layer including a plurality of carbon nanotubes; and an insulating layer on the carbon nanotube layer, wherein the plurality of carbon nanotubes are substantially all aligned along a longitudinal axis of the base substrate. A method of manufacturing the ultraconductor includes: preparing a base substrate; depositing a plurality of carbon nanotubes on the base substrate to form a carbon nanotube layer; depositing an insulating layer on the carbon nanotube layer, wherein the plurality of carbon nanotubes are substantially all aligned along a longitudinal axis of the base substrate.
