An X-ray analyzer includes an X-ray source, a straight tube type multi-capillary, a flat plate spectroscopic crystal, a parallel/point focus type multi-capillary X-ray lens, and a Fresnel zone plate. A qualitative analysis is performed over an area on the sample, the flat plate spectroscopic crystal and the Fresnel zone plate are removed from the X-ray optical path, and X-rays are collected by the multi-capillary lens and the sample is irradiated. When analyzing the chemical morphology of an element, the multi-capillary lens retracts from the optical path, the source rotates, and the flat plate spectroscopic crystal and the Fresnel zone plate are inserted on the optical path. A narrow sample area is irradiated by the Fresnel zone plate with X-rays having energy extracted from the flat plate spectroscopic crystal. This makes it possible to carry out accurate qualitative analysis on the sample and perform detailed analysis of more minute parts.
