To heat a furnace evenly without heating dry-distilled materials directly by induction heating when treatment of metallic wastes is carried out.
In the induction heating dry distillation furnace in which the dry-distilled materials 6 in the furnace 1 are dry-distillation treated by induction-heating the cylindrical furnace 1 with a heating coil 2 arranged outside of it, a top end part 1a and a bottom end 1b of the furnace are extended upward from an upper surface X and downward from a lower surface Y of the dry-distilled material 6, and the heating coil 2 is set at a height at which the top end face and the bottom end face of the heating coil 2 are respectively positioned between the upper end surface and the lower end surface of the furnace 1 and the upper surface and the lower surface of the dry-distilled material 6. By this, the dry-distilled materials are not directly heated by the heating coil 2 magnetic flux entering the furnace, and the upper and lower ends of the furnace 1 can surely be raised to a prescribed temperature.
