1. A carbon nanotube aggregate having a three-dimensional shape comprising:
a first surface, a second surface and a side surface;
wherein
a carbon nanotube of the first surface has a Herman orientation coefficient greater than −0.1 and smaller than 0.2,
a carbon nanotube of the second surface has a Herman orientation coefficient greater than −0.1 and smaller than 0.2,
a carbon nanotube of the side surface has a degree of orientation in which a Herman orientation coefficient is 0.2 or more and 0.99 or less,
the first surface and the second surface are mutually arranged in parallel and the side surface is perpendicular with respect to the first surface and the second surface,
at least one of the first surface or the second surface comprises a network of carbon nanotubes, and
a pore volume is 5 mL/g or more at a pore size where the differential pore volume of the carbon nanotube aggregate having a three-dimensional shape is a maximum.
