Abstract: PROBLEM TO BE SOLVED: To provide a method of producing a silicon carbide single crystal, which is able to stabilize hourly fluctuations of gaseous raw materials to be supplied. SOLUTION: In a method of producing a silicon carbide single crystal, which comprises transporting a Si-containing gas and a C-containing gas to a SiC seed crystal 3 and growing the SiC single crystal on the SiC seed crystal 3 in a crucible 1, a Si-raw material 4 being a source for supplying the Si- containing gas and a C-raw material 5 being a source for supplying the C- containing gas are separately arranged, and the Si-containing gas evaporated from the Si-raw material 4 is brought into contact with the C-raw material 5 and then the gas thus treated is supplied to the SiC seed crystal 3.  Thus, it becomes possible to stably supply C to the SiC seed crystal 3 by using the Si-raw material and the C-raw material and stably evaporating the Si-containing gas from the Si-raw material 4 at growing time, because the evaporated Si- containing gas reacts with carbon at the surface of the C-raw material 5 to form Si2C and SiC2. Accordingly, the hourly fluctuations of the gaseous raw materials to be supplied can be stabilized.
