An X-ray generating device includes an electron-beam generator, a target assembly group, and an electron-beam focusing unit. The electron-beam generator generates electron beams. The target assembly group includes a plurality of target assemblies that are arranged along a straight line in a direction in which X-rays are output; each of the target assemblies includes a target and a supporting member; the target generates X-rays from one of the electron beams generated by the electron-beam generator; and the supporting member supports the target by being disposed adjacent thereto. The electron-beam focusing unit focuses the electron beams onto the targets included in the target assembly group so that X-rays are generated in each of the target assemblies and output along the straight line after passing through the target assemblies. |
