<p>The present invention relates to an X-ray tube (1A), having a structure enabling capturing of a clear magnified transmission image and enabling increase of a magnification factor of the magnified transmission image, and an X-ray source including the X-ray tube. In the X-ray tube (1A), X-rays are generated by making electrons from an electron gun (11) incident onto an X-ray target of an anode (5), disposed inside an anode housing unit(3), and the generated X-rays are taken out from an X-ray emission window. In particular, the anode housing unit (3) has a pair of conductive flat portions (13d) disposed parallel to a reference plane, orthogonal to an electron incidence surface (5d) of the X-ray target, and so as to sandwich the X-ray target. The reference plane contains a first reference line, joining an electron emission exit center of the electron gun (11) and an electron incidence surface center of the X-ray target, and a second reference line, being a straight line intersecting the first reference line on the electron incidence surface (5a) of the X-ray target and joining the electron incidence surface center and an X-ray emission window center.</p> |
