Summary:PROBLEM TO BE SOLVED: To provide an X-ray tube in which prevention of static charge to an enclosure by recoil electrons is possible. SOLUTION: In the X-ray tube equipped with a cathode 1 having a filament that discharges thermal electrons 6 and a focusing body 5 that focuses thermo-electrons 6 from the filament, a target 2 arranged opposing to the cathode 1, an anode 3 to support the target 2, and the enclosure 9 composed of an insulator that encapsulates the cathode part 1 and the anode 3 in a vacuum air-tight state, an electron insulation shield 10 is equipped which prevents adhesion of the recoil electrons to the enclosure 9 from the anode 3 arranged in a space between the target 2 and the enclosure 9.
