A single crystal manufacturing apparatus has a pulling mechanism and a magnetic field generating unit. The pulling mechanism grows a single crystal by inserting a seed crystal into a melting liquid of a single crystal raw material and pulling the seed crystal from the melting liquid at a predetermined speed. The generating unit has a pair of superconductive magnets for applying a magnetic field to the melting liquid. The magnetic field applied from the magnets suppresses a thermal convection in the vicinity of the surface of the melting liquid and allows the thermal convection in the region of the melting liquid below the surface thereof. |
