Abstract
There is provided a carbon nanofiber aggregate capable of suppressing scatter and having excellent dispersibility and filling property in a thermoplastic resin. A carbon nanofiber aggregate has a maximum void volume P1 (cm/g) at a pore diameter of 2,500 nm or more and 100,000 nm or less and a maximum void volume P2 (cm/g) at a pore diameter of 6 nm or more and less than 2,500 nm in pore distribution data measured by mercury porosimetry. The maximum void volume P1 and the maximum void volume P2 satisfy a specific relationship.
