Abstract
A single crystal manufacturing device, in which there are provided a crucible having a melting part for holding a molten liquid of a raw material and a nozzle part for continuously taking out a predetermined amount of the molten liquid by the action of gravity; a heater for heating the raw material to melt it in the melting part; and temperature control means for heating the nozzle part to take out the molten liquid of the raw material from the nozzle part and for providing as large a thermal gradient as possible in the solid-liquid interface between the molten liquid taken out from the nozzle part and a grown single crystal continuous to the molten liquid. The crucible can be double-structured. A guide pipe filled with fibrous material may be provided between the nozzle and the rollers of the grown single crystal.
