Abstract
A carbonization method of carbonizing precursor fibers that are being conveyed includes carbonization performed using a plurality of carbonization furnaces for heating fibers arranged in the direction in which the fibers are conveyed. The plurality of carbonization furnaces include at least one carbonization furnace that heats the fibers using plasma when the fibers are passing through the inside of the at least one carbonization furnace. A carbon fiber production method includes a carbonization process of carbonizing precursor fibers that are being conveyed. The carbonization process is performed with the above carbonization method.
