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), an electron source including metal wires (7a, 7b, 7c) having carbon based electron emission materials (6a, 6b, 6c) and arranged in the vacuum enclosure (5) by being held, at the opposite ends thereof, by the vacuum enclosure (5), a target material (15) provided in the vacuum enclosure (5) opposite to the electron source for generating X-rays in response to incidence of electrons from the electron source, a through hole (13) for taking out the X-rays generated from the target material (15) to the outside and a silicon thin film (14) fixed to the vacuum enclosure (5), and an extraction electrode (11) provided between the electron source and the target material (15) on the inner surface (3a) of the vacuum enclosure (5).
