Zusammenfassung:A manufacturing method of monocrystalline silicon includes: melting silicon housed in a quartz crucible into a silicon melt by heating the quartz crucible with a heating unit; dipping a seed crystal into the silicon melt in the quartz crucible to bring the seed crystal into contact with the silicon melt; and pulling up the seed crystal to grow monocrystalline silicon. In the pulling-up, a formation of a straight body of the monocrystalline silicon is started at a power consumption of the heating unit being equal to or more than 10000 kWh to grow an entirety of the monocrystalline silicon.
