To correctly acquire image data of an inspected article by preventing a difference in shade between images caused by a difference in position or sensitivity between sensor elements. An X-ray generation source irradiates an inspection region where an inspected article passes with an X-ray. X-ray detection means receives the X-ray passing through the inspection region using a plurality of sensor elements. Image data generation means generates image data of the inspected article from an output of the X-ray detection means. Incidence condition changing means changes two or more kinds of X-ray incidence conditions common for all of the sensor elements of the X-ray detection means in a state of absence of the inspected article in the inspection region. Correction data generation means acquires correction data that is needed for making a shade of an image uniform for each incidence condition.
