PROBLEM TO BE SOLVED: To prevent a detecting means for detecting secondary X-rays generated from a sample, from detecting secondary X-rays outside of a detection object, generated from the interior of an X-ray tube. SOLUTION: This X-ray analysis apparatus is provided with the X-ray tube 5 for guiding primary X-rays (a) generated from an X-ray source 2, and the detecting means 7 for detecting the secondary X-rays (b) generated by irradiating the sample 10 with the primary X-rays (a) from the X-ray tube 5. A plate body 20a for suppressing the secondary X-rays (b) generated from the interior of the X-ray tube 5 is provided between the X-ray tube 5 and the detecting means 7 to prevent the detecting means 7 from detecting the secondary X-rays outside of the detection object, generated from the interior of the X-ray tube 5.
