Abstract
An X-ray tube includes a housing, an electron gun that emits an electron beam inside the housing, a target that generates an X-ray upon an incidence of the electron beam inside the housing, and a window member that seals an opening of the housing and that transmits the X-ray. The window member is formed in a plate shape from a single crystal diamond. A [100] direction of the single crystal diamond is in an intersection relationship with a thickness direction of the window member at an angle of less than 45 degrees.
