    摘要： Provided is an apparatus for manufacturing a vitreous silica crucible which has a structure which can reduce gaps between a partition wall and electrodes inserted into through-holes formed in the partition wall while enabling electrodes to move to adjust a heating temperature of arc discharge. A plate-shaped partition wall 15 is placed above the rotating mold 10. Electrodes 13 for heating and fusing are inserted into through-holes 16 penetrating in a thickness direction, and are directed toward the rotating mold 10. A rocking unit 40 is provided on an upper side of the partition wall 15 and rocks the electrodes 13 around virtual rocking axes P, and the virtual rocking axes P pass through the through-holes 16.
