The method for preparing a single crystal substrate comprises a step wherein a lower epitaxial layer is grown on a base substrate, a step wherein at least a part of an electric potential region in the lower epitaxial layer is optionally removed, a step wherein an electric potential prevention element is formed in the electric potential region that has been removed, and a step wherein an upper epitaxial layer is formed on the lower epitaxial layer on which the electric potential prevention element has been formed.
