PURPOSE:To obtain crystal having uniform characteristics in high reproducibility efficiently, by changing number of revolutions of a container having an electrically-conductive liquid for crystal growth, and controlling concentration of content of container constituting component. CONSTITUTION:The outer peripheral surface of the rotary container 2 having the electrically-conductive liquid 3 for crystal growth is provided with the electric heater 5 of the heating means 4 in a cylindrical face, a magnetic field is impressed to the liquid 3 from the magnetic field generating means 7 set at the outside of the heating means, and a DC current having a ripple current suppressed to <=4% is sent to the heater 5, to heat it. Number of revolutions of the container 2 is changed to control concentration of content of a container constituting component in crystal, and the single crystal seed 8 kept by the pulling chuck 9 is simultaneously pulled up to grow the single crystal 10.
