摘要: Provided is a production apparatus (100) for continuously producing aligned carbon nanotube aggregates on a substrate supporting a catalyst while continuously transferring the substrate. The production apparatus (100) includes gas mixing prevention means (12, 13) for preventing gas present outside a growth furnace (3a) from flowing into the growth furnace (3a). The gas mixing prevention means (12, 13) includes a seal gas ejection section (12b, 13b) so that the seal gas does not flow into the growth furnace through the openings of the growth furnace. The production apparatus prevents the outside air from flowing into the production apparatus, uniformly controls, within a range suitable to production of CNTs, a concentration distribution(s) and a flow rate distribution(s) of a raw material gas and/or a catalyst activation material on the substrate, and does not disturb gas flow as much as possible in the growth furnace.

摘要: A production method for growing a carbon nanotube assembly on a substrate having a catalyst on a surface thereof. In this production method, in each of a formation unit that carries out a formation step of reducing a catalyst on the substrate and a growth unit that carries out a growth step of growing a carbon nanotube assembly, the substrate is continuously being conveyed using conveyance units that convey the substrate by screw rotations. In carrying out the formation step and the growth step, these steps are carried out while the gas environments in these steps are prevented from mixing with each other.
