Abstract: A reactor 200 according to the present invention includes a heater storage section serving as a space section capable of accommodating a carbon heater to initial heating of silicon core wires. A carbon heater 13 is loaded in a deposition reaction space 20 in the reactor 200 only when necessary for initial heating of silicon core wires 12.

As a result, the carbon heater 13 is not unduly damaged in the reactor any longer and its deterioration is reduced. In addition, because of reduction in reaction with hydrogen gas in the reactor, the generation of methane is reduced, and thus carbon contamination of polycrystalline silicon is reduced.
