Abstract:
Provided is an X-ray generating tube with improved withstand voltage property by a simple structure, the X-ray generating tube including a cathode connected to one opening of an insulating tube and an anode connected to the other opening, in which a resistive film having a lower sheet resistance value than that of the insulating tube is disposed on an outer periphery of the insulating tube, and the cathode and the anode are electrically connected to each other via the resistive film.
