ABSTRACT:
The present invention relates to a carbon fiber having a novel structure in which the outer circumferential part of fiber section is constituted of an optically isotropic component and its central part is constituted of an optically anisotropic component or an optically anisotropic component partially containing optically isotropic component, which the carbon fiber shows no cracks at all, as well as to a process for producing said carbon fiber.
