Abstract
The present invention relates to an X-ray tube in which X-rays are generated by making electrons from an electron gun incident onto an X-ray target of an anode, disposed inside an anode housing unit, and the generated X-rays are taken out from an X-ray emission window. The anode has a straight main body and a protruding portion, extending along an axis line direction of the main body from a tip of the main body. An inclined surface, onto which the electrons emitted from the electron gun collide, and a pair of side surfaces, disposed in parallel while sandwiching the inclined surface, are formed on the protruding portion. A distance between the pair of side surfaces of the protruding portion is shorter than a width of the main body in the same direction as the distance.
