PROBLEM TO BE SOLVED: To provide a manufacture method for directly obtaining a single crystal member capable of being used as a single crystal substrate without passing through processes for cutting, grinding and the like. SOLUTION: This method for manufacturing a single crystal member comprises forming an amorphous film 2 on a single crystal substrate 1, selectively removing the surface of the single crystal substrate 1 by photolithography to form windows 3, bringing the windows 3 into contact with a supersaturated solution supersaturatedly containing a prescribed element to allow the epitaxial growth of single crystals 4 containing the element as a constituent in the direction vertical to the surface of the single crystal substrate 1 as seed crystal portions, and then stopping the contact of the single crystals with the supersaturated solution 5 to stop the epitaxial growth, thus obtaining the single crystal member having prescribed size and shape.
