Abstract:
An X-ray source includes an electron-beam generating unit that generates an electron beam, and a transmission type target electrode to be irradiated with the electron beam to generate X-ray radiation. A plurality of convex portions each having an inclined surface with respect to an incident direction of the electron beam is formed on a surface of the transmission type target electrode.
