PROBLEM TO BE SOLVED: To obtain a carbon fiber fine particle which is finely pulverized to have an average diameter of shorter than 10μm from a substandard article generated between manufacturing processes of carbon fiber, an industrial waste of carbon fiber, and a carbon fiber object such as a waste material article or the like. SOLUTION: The carbon fiber article is cut into a small size, ground, and finely pulverized to obtain the carbon fiber fine particle having an average diameter of shorter than 10μm. Moreover, the manufacture method and apparatus of the carbon fiber fine particle are characterized in that in obtaining the carbon fiber fine particle, the carbon fiber is cut into a small size, the carbon fiber cut into a small size is suctioned, collected, stored and finely pulverized by either of a jet mill, a ball mill, a bead mill grinder or the like which utilizes impact friction force making the carbon fiber fine particle before the utilization.
