摘要
A method for producing a carbon nanostructure aggregate having a large external specific surface area and a carbon nanostructure aggregate are provided. The method for producing a carbon nanostructure aggregate comprises supplying a source gas to a catalyst to grow a carbon nanostructure aggregate comprising a plurality of carbon nanostructures by a chemical vapor deposition method, wherein a gas derived from the source gas and brought into contact with the catalyst comprises: as a hydrocarbon to serve as a carbon source, at least one of: a hydrocarbon A having at least one acetylene skeleton, a hydrocarbon B having at least one 1,3-butadiene skeleton, a hydrocarbon C having at least one cyclopentadiene skeleton, and a hydrocarbon D having at least one allene skeleton, and carbon monoxide and carbon dioxide; and satisfies 0.01‰¤[CO]/[C]‰¤15 where [C] is a total volume concentration of carbon contained in the hydrocarbons A, B, C, and D, and [CO] is a volume concentration of carbon monoxide.
