PROBLEM TO BE SOLVED: To provide an X-ray tube in which dispersion of an emission emitted at the time of sealing an exhaust pipe into a container body is suppressed, thereby reducing effect on functions and performance.SOLUTION: An X-ray tube 10 includes an electron gun 11 and a vacuum case 12 having a container body 15 for housing the electron gun 11 therein. An exhaust pipe 24 to be sealed at a predetermined sealing portion 24a after exhaust from the container body 15 is connected to the container body 15. A trap part 27 for catching an emission A emitted into the exhaust pipe 24 at the time of sealing the sealing portion 24a is provided at a connection portion of the container body 15 connected with the exhaust pipe 24. |
