PROBLEM TO BE SOLVED: To make an incident angle of an X-ray with respect to a measurement object be a setting value accurately even though the measurement object has a complex shape.SOLUTION: By sticking a leveling instrument LV or a leveling instrument LH to a measurement spot of a measurement object OB to adjust the posture of the measurement object OB, the measurement spot of the measurement object OB is made horizontal. Then, from an X-ray diffraction measurement apparatus which can accurately adjust an angle to a gravity direction of the optical axis of an X-ray with respect to the measurement spot or which has the angle to the gravity direction of the optical axis of the X-ray fixed to a setting value, the X-ray is emitted and the generated diffraction light of the X-ray is received to image a diffraction ring. |
