Abstract
A carbon fiber composite material comprising 100 parts by mass of an elastomer, and 20 to 100 parts by mass of carbon nanofibers that have been oxidized and reduced in number of branch points. The carbon fiber composite material has a dynamic modulus of elasticity (E′) at 200° C. and 10 Hz of 10 to 1000 MPa, and a volume resistivity of 106 to 1018 ohms·cm.
