Abstract: A CNT aggregate formed from a plurality of CNT's is provided, the CNT aggregate having a storage modulus (G25° C.′) at 25° C. obtained by a dynamic mechanical analysis in a 1 Hz frequency in shear-mode of 104 Pa or more and 109 Pa or less, a loss modulus (G25° C.″) at 25° C. obtained by a dynamic mechanical analysis in a 1 Hz frequency in shear-mode of 103 Pa or more and 108 Pa or less, a damping ratio (tan δ(=G25° C.″/G25° C.′)) at 25° C. obtained by a dynamic mechanical analysis in a 1 Hz frequency in shear-mode of 10−3 or more and 1 or less, and a distribution maximum of a pore diameter calculated using a BJH method from an adsorption isotherm of liquid nitrogen of the CNT aggregate being 50 nm or less.
