An object of the present invention is to provide a method for producing carbonized fabric having flexibility and strength which can endure processing and having conductivity. To solve the problem, there is provided a carbonized fabric production method for producing a carbonized fabric by heating a fabric containing cellulose in a furnace, the method comprising: a fabric arrangement step of arranging the fabric in the furnace; a first temperature-increasing step of increasing the temperature of at least a fabric arrangement region in the furnace to a temperature that is closely below a carbonizing temperature of the fabric, while at least a fabric arrangement region in the furnace being adjusted to be in an inert atmosphere; a second temperature-increasing step of, after the first temperature-increasing step, increasing the temperature of at least the fabric arrangement region of in the furnace to a temperature in a range of from 1,200 °C to 1,400 °C, while at least the fabric arrangement region in the furnace being adjusted to be in a reducing atmosphere relative to at least the inert atmosphere in the first temperature-increasing step; a maintenance step of maintaining, for a predetermined period of time, the temperature in the furnace which has reached a temperature in a range of from 1,200 °C to 1,400 °C in the second temperature-increasing step; a temperature-decreasing step of gradually decreasing the temperature in the furnace after a lapse of the predetermined period of time; and a furnace-opening step of opening the furnace after the temperature in the furnace has become about 100 °C or less in the temperature-decreasing step. |
