The present invention provides a method for manufacturing a silicon carbide single crystal by sublimating a solid silicon carbide raw material in a growth container to grow a silicon carbide single crystal on a seed crystal substrate. The method includes: mixing a tantalum (Ta) powder with a carbon powder; attaching the mixture to the solid silicon carbide raw material in the growth container; and heating the resultant for sintering to form a tantalum carbide (TaC) coating film on a surface of the solid silicon carbide raw material. A silicon carbide single crystal is grown after or while the coating film is formed. Thereby, the present invention provides a method for manufacturing a silicon carbide single crystal with few carbon inclusions.
