Abstract
This method improves a carbon nanotube growth environment. In this method of manufacturing carbon nanotubes, the supply amount of catalyst activating material supplied in a carbon nanotube growing step is adjusted to the supply amount of catalyst activating material supplied at the time of maximum concentration of a gas component among multiple measurements made in the growing step, the gas component being at least one selected from the group consisting of hydrogen, methane, and ethane.
