    Abstract: An X-ray analytical apparatus of a wavelength dispersion type having a construction of essential parts improved using a microprobe of ion beam. An ion beam 10 is controlled to be deflected to scan in a fine region of a sample 3, a characteristic X-ray generated by irradiation of the ion beam is subjected spectro-process by a analyzing element 5 set to a predetermined radius of curvature by a curvature changing mechanism, and an X-ray having a specific wavelength selected by the spectro-process is detected by a proportional counter 7. When an angle of the analyzing element is set by a rotational stage to an incident angle of a specific X-ray determined by a detection element on the sample 3, a wide range of wavelength can be subjected to spectro-measured while the sample 3, the analyzing element 5 and the proportional counter 7 remain fixed in position. Since the proportional counter 7 is provided with a lengthy sensing portion, even if an incident position of the X-ray is changed, measurement can be made while a position of a detector remains fixed. Being a position sensitive type detector, incident position information of the X-ray different according to the wavelength can be removed, and the wavelength and strength of the X-ray can be measured while discriminating each X-ray quantum.
