Abstract
An X-ray generator includes an electron source generating an electron beam, a target generating an X-ray by a collision of the electron beam and extending in a direction orthogonal to the electron beam, and a cylindrical electrode covering a collision portion of the target to which the electron beam collides and having a bore allowing the electron beam to pass through. The electron source and the target are arranged in such a way that the X-ray is radiated in the direction orthogonal to an optical axis of the electron beam. A depression equivalent to a notch of the target is provided in a collision face side of the electron beam on the target and also in a reverse location of a tip of the target located on an outgoing radiation side of the X-ray relative to a collision location of the electron beam on the target.
