Claim Text:
1. An X-ray analyzer, comprising: a scanning unit for scanning a sample with a beam; an X-ray detector for detecting X-rays generated on the sample by the scanning; an element distribution obtaining unit for, from the detection result of the X-rays generated in an area on the sample scanned with the beam, obtaining intensity distribution of the X-rays whose energy or wavelength is included in a range of energy or wavelength set up in correspondence to an element contained in the sample and thereby obtaining distribution of the element; an intensity distribution acquiring unit for acquiring intensity distribution of X-rays whose energy or wavelength is not included in the range; an area specifying unit for specifying an area on the sample corresponding to a portion where the intensity of X-rays is not less than a predetermined intensity in the intensity distribution; a spectrum generating unit for generating a spectrum of X-rays generated in the specified area on the sample; an element identification unit for identifying an element contained in the sample on the basis of a peak included in the generated spectrum; and a setting unit for setting a range of energy or wavelength of X-rays corresponding to the identified element, wherein the element distribution obtaining unit obtains distribution of the element identified by the element identification means, in accordance with the range set by the setting means.
