摘要： To provide an X-ray generator capable of preventing electric corrosion and exerting stable performance over long periods. The X-ray generator includes: a rotary anticathode 1 having a rotary anticathode part 1a and a shaft part 1b; an anticathode accommodating case 2 including an air-tight case part 2a for keeping an area surrounding the rotary anticathode part in a vacuum atmosphere, and a journaling case part 2b for rotatively supporting the shaft part via a bearing; and an electric motor to rotatably drive the anticathode (target). A water-cooled jacket 7, through which cooling water for cooling the rotary anticathode part and the shaft part flows, is provided in the rotary anticathode. In the X-ray generator, an insulating bearing 18 of which at least one of an inner ring 18a, an outer ring 18b and a rolling element 18c is made of an insulating material is used as the bearing, and a conductive fiber brush 20 having a large number of conductive microfibers 22 serving as slide-contacting brush is arranged between opposing peripheral surfaces of the journaling case part of the anticathode accommodating case and the shaft part of the rotary anticathode, such that current is flown from the rotary anticathode to the anticathode accommodating case via the conductive fiber brush 20. In addition, pure water or ion-exchange water having low electric conductivity is used as cooling water flown through the water-cooled jacket.
