PPROBLEM TO BE SOLVED: To easily perform quantitative analysis in a short time by easily generating an analytical curve in a short time. PSOLUTION: A sample to be tested is scanned and read to determine a diffraction intensity profile, determine an integrated quantity of peak waveforms contained in the profile, and determine a content on the basis of an analytical curve and the integrated quantity in a quantitative analysis method. A standard sample having a known content is measured by the prescribed reading step width (0.02) within a wide scanning range (11.0213.2) to determine diffraction line profiles P1-P5. A measured quantity (I) by the reading step with is stored for every standard sample. On the basis of measurement results of the sample to be tested, a quantitative measurement scanning range is determined. An integrated value within the same range (2) as the quantitative measurement scanning range is determined by computations on intensity data by the step width on the stored standard sample to determine an analytical curve on the basis of the integrated quantity and the known content of the standard sample.
