A graphitization furnace (100) includes: split electrodes (122) that are conductive and are provided so as to be freely movable; crucibles (120) that are conductive and that contain carbon powder, with a bottom end portion (122a) of each split electrode (122) being buried in the carbon powder; upper electrodes (190) that are positioned so as to face a split electrode (122); lower electrodes (192) that are positioned so as to face a crucible (120); and a power supply unit (132) that, when a bottom end portion (190a) of an upper electrode (190) is placed in contact with a top end portion (122b) of a split electrode (122) and a top end portion (192a) of a lower electrode (192) is placed in contact with a base portion (120b) of a crucible (120), applies a voltage between the upper electrode (190) and the lower electrode (192). |
