Abstract
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.
