Abstract
The present invention provides an X-ray generator including an X-ray tuberadiating primary X-rays Xto a specimen S, a housingaccommodating the X-ray tube, an X-ray radiation area controllerlimiting the radiation area of the primary X-rays Xfrom the X-ray tubeto the specimen S, and a device holderholding the X-ray radiation area controllerwith respect to the housing. The X-ray tube includes a case, an electron ray sourcegenerating electron rays, and a target unithaving a base fixed to the case and receiving electron rays through a protruding free end. The device holder has a fixed-basefixed to the housing, directly under the base of the target unit, and a supporting extensionextending from the fixed-base in the protrusion direction of the target unit and supporting the X-ray radiation area controller.
