Abstract
Provided is a fibrous carbon nanostructure with which a dispersion liquid having high dispersibility can be obtained without using a dispersant and thus with which a homogeneous film that is free of clumps can be obtained. In temperature programmed desorption of the fibrous carbon nanostructure, carboxyl group-derived carbon dioxide desorption among carbon dioxide desorption at from 25° C. to 1,000° C. is more than 1,200 μmol/g.
