Abstract
A method for manufacturing a carbon nanostructure according to the present invention includes a preparation step of preparing a base body, an oxidization step and a step of growing a carbon nanostructure. In the step of preparing a base body, a base body with at least a part of a contact portion or an integral portion of a catalyst member and a separation member having been oxidized is prepared. In the step of growing a carbon nanostructure, a carbon nanostructure is grown in a separation interface region between the catalyst member and the separation member. The step of growing a carbon nanostructure includes at least one of a step of locally supplying a source gas to a portion of the catalyst member facing the separation interface region where the carbon nanostructure is being grown, and a step of locally heating the separation interface region.
