To provide an X-ray analyzer and an X-ray analysis method that have improved operability for locating a measurement position and can measure distance precisely.

The X-ray detector includes: an X-ray bulb 2 for applying primary X rays X1 to an irradiation point on a sample S; an X-ray detector 3 for detecting characteristic X rays and scattered X rays radiated from the sample S for outputting a signal including energy information of the characteristic X rays and scattered X rays; an analyzer 4 for analyzing a signal; a first observation system 5 capable of optically observing an area on the sample S to determine the irradiation point P1; and a second observation system 6 that has a depth of field smaller than that of the first observation system 5 and can observe a narrow area optically and measure distance to the determined irradiation point P1 by adjusting a focus.
