A method of manufacturing a single crystal is provided with a raw material melting step of heating a silicon raw material in a quartz crucible using a carbon heater to generate a silicon melt; and a crystal pull-up step of pulling up a single crystal from the silicon melt generated by the raw material melting step, wherein the silicon raw material is heated with the maximum surface temperature of a first part of the heater that is positioned above at least the upper end of the quartz crucible maintained below 1500° C. in the raw material melting step.
