Abstract

An X-ray tube for irradiating X-rays, especially, an X-ray tube having a structure suitable for irradiating X-rays over a wide range. An X-ray tube (1) comprises a vacuum enclosure (5) including an insulating member at least partially, an electron source (8) where a carbon based electron emission material (6) is arranged on the surface of a metal mesh material (7) provided along the inner surface (3a) of a lower face plate (3) made of an insulating member, a target material (15) provided in the vacuum enclosure (5) opposite to the electron source (8) for generating X-rays in response to incidence of electrons from the electron source (8), an upper face plate (2) fixed to the vacuum enclosure (5) and functioning as a window for taking out the X-rays generated from the target material (15) to the outside, and an extraction electrode (11) secured between the electron source (8) and the target material (15) in the vacuum enclosure (5).
