PROBLEM TO BE SOLVED: To provide a technique for radiating heat generated in an aperture unit of an X-ray source for an X-ray apparatus.SOLUTION: An X-ray source includes: a conductor member 15A disposed between an electron source and a target 14 and focusing electrons on a predetermined position while accelerating the electrons; and an aperture unit 16 including an aperture part 16a restricting a part of the electrons focused by the conductor member 15A. The aperture unit 16 has an extension part which extends toward an outside along a second direction crossing a first direction in which the electrons are directed toward the target 14, and is brought into contact with a housing 27. |
