Abstract
Provided is a carbon nanotube aggregate excellent in gripping force in a wide temperature range including high-temperature conditions. The carbon nanotube aggregate of the present invention is a carbon nanotube aggregate of a sheet shape, including a plurality of carbon nanotubes, wherein the carbon nanotube aggregate satisfies the following condition for FFM differential voltages when a frictional curve is obtained by scanning a front surface and/or a back surface of the carbon nanotube aggregate with a probe of a scanning probe microscope under a state in which the probe is brought into contact therewith: a ratio of an FFM differential voltage at 210° C. to an FFM differential voltage at 25° C. is from 0.3 to 5.
