Provided is a SiC single crystal wafer, which is manufactured from a SiC single crystal ingot grown by the sublimation-recrystallization method, and which brings about high device performance and high device manufacture yield when used as a wafer for manufacturing a device. The SiC single crystal wafer has, in a surface thereof, a basal plane dislocation density of 1,000 dislocations per cm2 or less, a threading screw dislocation density of 500 dislocations per cm2 or less, and a Raman index of 0.2 or less. Further provided is a method of manufacturing a SiC single crystal ingot, including controlling heat input from a side surface of the single crystal ingot during growth of a single crystal, to thereby grow the crystal while changes in the temperature distribution of the single crystal ingot are reduced.
