A method of production of SiC single crystal using the solution method able to stably maintain flatness of a growth surface, prevent polycrystallization, and grow a large sized SiC single crystal is provided. A method of growing a hexagonal SiC single crystal starting from a hexagonal SiC seed crystal held directly under a melt surface of an Si melt in a graphite crucible by maintaining in the Si melt a temperature gradient such that the temperature falls from the inside toward the melt surface of the Si melt, characterized by: growing said SiC single crystal on a surface of said SiC seed crystal, which surface is inclined at a selected off angle from a (0001) plane of the SiC seed crystal in a [1-100] direction of the SiC seed crystal. The off angle is preferably 1 to 30°, while growing the SiC single crystal on the (1-100) surface where the off angle is 90° is most preferable.
