Provided is a method for manufacturing carbon nanotubes with which it is possible to easily modify the manufacturing conditions, easily obtain carbon nanotubes having a diameter, length, crystallinity, density, and form suitable for various applications, and improve spinnability for the purpose of processing the carbon nanotubes into uni-directionally oriented carbon nanotube sheets. This method for manufacturing carbon nanotubes comprises producing, by a chemical vapor deposition process using a mixture of ferrous chloride and ferric chloride as a catalyst, a multitude of carbon nanotubes perpendicularly oriented on a substrate, wherein the size and density of the catalyst deposited onto the substrate are controlled by controlling the mixture ratio of ferrous chloride and ferric chloride. |
