This X-ray radiographing method is used for an X-ray radiographing device made up of an X-ray generator and a detector provided in a position opposed to the X-ray generator and used for radiographing the sample put between the X-ray generator and the detector. A tube current of the X-ray generator is varied at least two times and received by the detector. At least two images received by the detector are synthesized.
