As a transparent conductive material for forming a transparent flexible conductive film, etc., it relates to a carbon fiber production method that can be suitably used, and more specifically, a carbon fiber production method in which the outermost surface is composed of graphene ends. A step of calcining the fiber of the organic compound so as to contain residual hydrogen, and the organic compound fiber after the calcining is placed in a sealed container made of a heat-resistant material, and a pressurized gas atmosphere is put together with the container The manufacturing method which includes the process of using the used hot isostatic-pressure pressurization, and is the maximum reach | attainment temperature in hot isostatic-pressurization processing is 1000 to 2000 degreeC, and relates to the carbon fiber obtained by this manufacturing method. |
