Abstract
An apparatus of the present invention for producing an aligned carbon-nanotube aggregate is an apparatus for producing an aligned carbon-nanotube aggregate by synthesizing the aligned carbon-nanotube aggregate on a base material having a catalyst on a surface thereof, the apparatus including: a formation unit that processes a formation step of causing an environment surrounding the catalyst to be an environment of a reducing gas and heating at least either the catalyst or the reducing gas; a growth unit that processes a growth step of synthesizing the aligned carbon-nanotube aggregate by causing the environment surrounding the catalyst to be an environment of a raw material gas and by heating at least either the catalyst or the raw material gas; and a transfer unit that transfers the base material at least from the formation unit to the growth unit. Thus provided is a production apparatus and a production method that are capable of improving efficiency in the production of aligned CNT aggregates by preventing a decrease in production volume and deterioration in quality of aligned CNT aggregates in serial production and by making it easy to increase the size of the apparatus.
