Abstract: Disclosed are a cartridge-type X-ray source apparatus and an X-ray emission apparatus using the same. The X-ray source includes: a cathode electrode provided with an electron emission source by using a nanostructure; an anode electrode having a target emitting X-rays by electron collision; and a housing forming an external appearance, and exposing a cathode electrode terminal connected to the cathode electrode and an anode electrode terminal connected to the anode electrode to an outside thereof, wherein the cathode electrode terminal and the anode electrode terminal differ from each other in at least one of exposure direction, height, size, and shape.
