Abstract
Provided is a fibrous carbon nanostructure that is easy to surface modify. A symmetry factor of a peak of a first derivative curve of a thermogravimetric curve obtained through thermogravimetric analysis of the fibrous carbon nanostructure in a dry air atmosphere is 3.70 or less. The first derivative curve of the thermogravimetric curve can be a temperature derivative curve of the thermogravimetric curve or a time derivative curve of the thermogravimetric curve.
