Provided is an X-ray generation device including an X-ray tube and a high-voltage generation unit arranged inside a housing and also having insulating oil filled in the housing, which uses no lead and is small in size, thereby achieving a reduction in manufacturing cost, and which also has high cooling performance. An X-ray generation device 1 includes an X-ray tube 2 and a high-voltage generation unit 3 inside a housing 8 and also has insulating oil 4 filled in the housing 8, the X-ray tube 2 being configured to generate an X ray, the X-ray generation device 1 characterized in that the X-ray tube 2 is arranged inside an X-ray tube holder 10, a material of the X-ray tube holder 10 contains at least bismuth oxide and a resin, and the X-ray tube holder 10 includes an opening and a plurality of slits 11, the opening being provided in a portion corresponding to an X-ray irradiation window 7 through which the X-ray tube 2 applies the X ray, the slits 11 allowing the insulating oil 4 to circulate between an inside and an outside of the X-ray tube holder 10. |
