PROBLEM TO BE SOLVED: To provide an X-ray tube of a rotating anode type, in which a target part consisting of cerium does not come off the base material. SOLUTION: The X-ray tube is provided with a cathode which generates an electron beam, a target part which generates X-rays as the electron beams collide, an anode matrix which supports the target part, a rotating device which makes the anode base material rotate, and an outer housing which supports the cathode, the target part, and the anode matrix inside vacuum. The target part consists of cerium and the anode base material is made of a material having melting point which is higher than that of the target part. COPYRIGHT: (C)2009,JPO&INPIT
