Carbon-based fine structure group, the aggregate of carbon-based fine structure, its use and a method of manufacturing the same

An aggregate in which a plurality of carbon-based microstructures are assembled in a state where attracted to each other by strong interaction, provides a collection of length that can improve its handling and workability. Aggregate of carbon-based microstructures of the present invention has a plurality of carbon-based microstructures are assembled, each carbon-based microstructures are aligned in the same direction.
