Abstract
A carbon nanotube assembly satisfies at least one of the following conditions (1) to (3): (1) an FT-IR spectrum of a CNT dispersion obtained by dispersing the CNT assembly has a peak based on plasmon resonance of the CNTs in a wave number range of greater than 300 cm−1 and 2000 cm−1 or less; (2) the highest peak in a differential pore capacity distribution of the CNT assembly is located within a pore size range of more than 100 nm and less than 400 nm; and (3) a two-dimensional spatial frequency spectrum of an 10 electronic micrographic image of the CNT assembly has at least one peak within a range of 1 μm−1 or more and 100 μm−1 or less.

A carbon nanotube assembly, the carbon nanotube assembly satisfying at least one of the following conditions (1) to (3):
- (1) a spectrum obtained by a Fourier transform infrared spectroscopic analysis on a carbon nanotube dispersion obtained by dispersing the carbon nanotube assembly so that a bundle length is 10 μm or more, has at least one peak based on plasmon resonance of the carbon nanotube dispersion in a wavenumber range of more than 300 cm−1 and 2000 cm−1 or less;
- (2) a highest peak in a differential pore capacity distribution measured on the carbon nanotube assembly is located within a pore size range of more than 100 nm and less than 400 nm;
- and
- (3) a two-dimensional spatial frequency spectrum of an electron microscopic image of the carbon nanotube assembly has at least one peak within a range of 1 μm−1 or more and 100 μm−1 or less.
