Abstract
A direct resistance heating apparatus includes first and second electrodes arranged with a space provided therebetween, a power supply electrically connected to the electrodes, an electrode moving mechanism configured to move, in a state in which the electrodes are in contact with a workpiece and in a state in which current is applied from the power supply to the workpiece through the electrodes, at least one of the electrodes along an opposing direction in which the electrodes are opposed to each other, first and second holders configured to hold the workpiece such that, in a state in which the at least one of the electrodes is moved, a heating target region of the workpiece located between the electrodes is held between the holders in the opposing direction, and a holder moving mechanism configured to move at least one of the holders to pull the workpiece along the opposing direction.
