Abstract: Provided is an SiC-monocrystal growth crucible that includes, at the interior thereof, a monocrystal installation part and a raw-material installation part, and that serves as a crucible for obtaining an SiC monocrystal by means of sublimation, wherein the gas permeability of a first wall of the crucible, which surrounds at least a portion of a first region positioned closer to the raw-material installation part relative to the monocrystal installation part, is lower than the gas permeability of a second wall of the crucible, which surrounds at least a portion of a second region positioned on the opposite side from the raw-material installation part relative to the monocrystal installation part.
