Graphitization furnace and method for producing graphite

A graphitization furnace comprising:

• split electrodes that are conductive and are provided so as to be freely movable;
• crucibles that are conductive and that contain carbon powder, with a bottom end portion of each split electrode being buried in the carbon powder and with a top end portion of the split electrodes protruding from the carbon powder;
• upper electrodes that are positioned such that a bottom end portion thereof faces the top end portion of a split electrode;
• lower electrodes that are positioned such that a top end portion thereof faces a base portion of a crucible;
• and
• a power supply unit that, when the bottom end portion of an upper electrode is placed in contact with the top end portion of a split electrode and the top end portion of a lower electrode is placed in contact with the base portion of a crucible, applies a voltage between the upper electrode and the lower electrode.
