Abstract
A high-molecular weight carbon material in which cylindrical high-molecular weight carbon materials in the form of a cylindrical tube are bonded through a soccer ball-like spherical high-molecular weight carbon material as a point of junction, the respective cylindrical high-molecular weight carbon materials being formed by rolling a plane network composed of a benzene shell-like hexagonal molecule formed of covalent-bonded carbon atoms, and the soccer ball-like spherical high-molecular weight carbon material being formed of material including five- and six-membered carbon rings. The high-molecular weight carbon material is useful as a material for various functional devices.
