The insertion position of the protecting pipe 7 is preferably a position corresponding to the heater 8 outside the pipe 1 at the center of the furnace. When He and SF6 are fed from the feed opening 2, SF6 is decomposed at a high temperature and reacted in the pipe to evolve fluorine. The fluorine is reacted with H2O emitted from soot to give fluorine doped transparent glass. In this operation, fluorine is brought into contact with the inner wall of the protecting pipe 7, and the pipe 1 at the center of the furnace is protected from corrosion with fluorine since a part of the inner wall 1a of the pipe at the center of the furnace to be easily corroded with fluorine is prevented from being brought into contact with fluorine by the protecting pipe 7.
