摘要： Provided is a carbon fiber manufacturing method including a surface treatment step of ejecting an ozone solution in which ozone is dissolved in solvent from a fluid ejecting port toward a carbon fiber bundle and causing the ozone solution to pass between single fibers of the carbon fiber bundle so as to contact surfaces of the single fibers so that the surfaces of carbon fibers are treated by the ozone solution. Also, provided is a carbon fiber subjected to a surface treatment by the carbon fiber manufacturing method.
