PROBLEM TO BE SOLVED: To obtain an X-ray element-mapping device that can easily and accurately map a cylindrical sample. SOLUTION: An X-ray element-mapping device D is equipped with a sample stage 1 for placing a sample, an X-ray tube 2 for applying X rays to the sample, and an X-ray detector 3 for detecting a fluorescent X rays being generated in the sample by applying the X rays. In this case, a cylindrical sample S is rotatably retained around the axis center on the sample stage 1, and the sample stage 1 is freely moved in the axis center direction of at least the cylindrical sample S.
