Abstract
According to one embodiment, an X-ray tube includes a vacuum enclosure in which an output window which transmits X-rays is formed, an anode target provided in the vacuum enclosure so as to oppose the output window, a cathode filament provided in the vacuum enclosure, that emits electrons to be irradiated onto the anode target, a power feed section to which a high voltage cable is connected, and an insulating portion that covers the power feed section and the high-voltage cable with an insulating material, and the power feed section includes a contact surface with which a distal end surface of the high-voltage cable is brought into contact, and an angle formed by the contact surface and the side surface of the high-voltage cable is an acute angle.
