The present invention provides an X-ray source. The X-ray source includes a cathode having an emitter configured on an upper surface thereof; a gate electrode disposed on the cathode; a target formed to have a focal spot size; and an anode having the target to a lower surface thereof, having an oxide film formed on the surface of the periphery thereof to which the target is attached, and including aluminum. Thus, the manufacturing costs of the X-ray source may be reduced, and the manufacturing process thereof may be simplified. |
