<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a silicon single crystal by which the melting time of a silicon raw material can be shortened and the service life of a quartz crucible can be extended. Ž<P>SOLUTION: A nonproduct part 9 derived from a silicon single crystal 4 is used in an amount of ≥10 wt.% of the total weight of a silicon raw material being filled into a crucible 1, then the nonproduct part 9 and polycrystalline silicon 8 are melted in the crucible 1 to obtain a melt 3, and thereafter, a silicon single crystal 14 is pulled from the melt 3. Thereby, when the silicon raw material is melted, melting of the whole silicon raw material is facilitated because the nonproduct part 9 melts in an early stage. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
