An oriented single-walled carbon nanotube bulk structure that has a high specific surface area, high purity, and has achieved a dramatic increase in height or length, and a method for producing the same. A single wall comprising a plurality of aligned single-walled carbon nanotubes and having a specific surface area of 800 to 2500 m 2 / g and a purity measured by fluorescent X-rays of 98% or more. Carbon nanotube bulk structure. The structure is formed by controlling the thickness of the metal catalyst and providing the metal catalyst on a substrate, using a carbon compound as a carbon source in the reaction atmosphere gas from a plurality of carbon nanotubes from the metal catalyst, and a reaction atmosphere. It is formed by adding water vapor, oxygen, ozone, an oxygen-containing compound having a low carbon number, or a mixed gas thereof and orienting it in a predetermined direction by a vapor phase growth method.
