Claim 7:
8. A method of producing a silicon rod, comprising the steps of:
obtaining a silicon rod including one or more straight barrel portions by allowing silicon to be deposited on a silicon filament by passing electric current through the silicon filament in a reactor which includes at least a pair of electrodes and which is supplied with a source gas for silicon deposition, the silicon filament being connected to the pair of electrodes at both ends thereof;
connecting, to a support part, one or more first cords which are configured to pull up the support part and which are equal in number to or greater in number than a silicon rod, the support part being used to support the silicon rod so as to take the silicon rod out of the reactor;
pulling up the support part;
supporting the silicon rod by clamping one or more end portions of the silicon rod with the support part; and
holding the silicon rod by wrapping one or more second cords around the silicon rod, the one or more second cords being connected to the one or more first cords.
