Abstract: Provided are a heating furnace and a graphite production method both of which allow a carbonization step and a graphitization step to be consecutively performed. The heating furnace is a heating furnace for producing graphite from a polymeric material, and includes a heating furnace body for subjecting the polymeric material to heat treatment. The heating furnace body includes a closed vessel for containing the polymeric material. A gas outlet pipe is connected to the closed vessel, the gas outlet pipe being for letting, out of the heating furnace body, a pyrolytic gas generated from the polymeric material.
