The object of the present invention is to provide a method for fixing a silicon carbide seed crystal and a method for producing a silicon carbide single crystal which can produce a silicon carbide single crystal having high quality and no penetration defects, and the present invention provides a method for fixing a silicon carbide seed crystal on a pedestal including: a step of mirror polishing a surface of a pedestal on which a silicon carbide seed crystal is to be fixed; a step of irradiating atoms or ions to at least one of a seed crystal-side surface of the pedestal on which the silicon carbide seed crystal is to be fixed and a pedestal side-surface of the silicon carbide seed crystal which is to be fixed on the pedestal, in a vacuum; and a step of directly connecting the seed crystal side-surface of the pedestal and the pedestal side-surface of the silicon carbide seed crystal by bringing them into close contact and applying pressure to them in a vacuum.
