PROBLEM TO BE SOLVED: To provide an X-ray tomography system wherein tomography and general penetrative photography can be performed. SOLUTION: An X-ray tube supporting arm 22 which can rotate around a vertical axis J1 is disposed at the bottom end of a column 21 of an X-ray tube suspension device 2. An X-ray tube 1 is fixed through a rotation section 24 to a leading edge of a sliding section 23 which is slidably disposed at the X-ray tube supporting arm 22. The rotation section 24 rotates the X-ray tube 1 around a tube axis J2 and an axis J3. The X-ray tube supporting arm 22 is rotated around the vertical axis J1 and a photography apparatus 33 is rotated to be synchronized with the above rotation so that a center section 103 draws a circular orbit around the vertical axis J1 after the sliding of the sliding section 23 is stopped in the case of a circular orbit photography.
