PROBLEM TO BE SOLVED: To provide a simple method capable of realizing highly accurate machining and a jig for the method in a method for adjusting an azimuth of a single crystal to a target azimuth. SOLUTION: The azimuth of the single crystal is measured by attaching the single crystal to a crystal holder 9 having a single crystal attaching face parallel with a bottom face and an optical mirror face in a plane parallel with the single crystal attaching face. Angular deviation θ from the target azimuth is precedently specified from an azimuth of the crystal to the optical mirror face. An attaching angle of the crystal holder is adjusted on the basis of the deviation by an optical parallel and an autocollimator, and the single crystal is adjusted and corrected to the desired azimuth by removing a deviation amount by machining.
