An X-ray inspection apparatus comprising: an X-ray source; an X-ray detector that is disposed to face the X-ray source with an inspection space interposed therebetween; a stage having a stage face, said stage that is movable to any position in the inspection space by a three-dimensional movement mechanism such that an observation region of an inspection target object placed on the stage face of the stage is locatable on an X-ray optical axis connecting the X-ray source to the X-ray detector, and an X-ray fluoroscopic image of the inspection target object may be captured and displayed on a display device; a dose rate calculation unit for obtaining a reference dose rate for at least one position in the inspection space under a tube current and a tube voltage used as references, and that stores the reference dose rate as reference dose rate data obtained in advance, and that is configured to calculate a dose rate at any position in the inspection space as inspection space dose rate data on the basis of the reference dose rate data and a tube current and a tube voltage used for inspection of an inspection target object; a stage face information storage unit that stores stage face information including a stage reference point defined for the stage and relative position information for defining a range of the stage face; an irradiation history monitoring unit configured to monitor a movement locus of the stage reference point at each time point from starting of X-ray irradiation to ending of X-ray irradiation, and configured to store the movement locus as irradiation history information; a stage face cumulative irradiation dose calculation unit that is configured to calculate a cumulative irradiation dose at each position on the stage face of the stage on the basis of the irradiation history information, the stage face information, and the inspection space dose rate data, and that is configured to store the cumulative irradiation dose as cumulative irradiation dose distribution data; a stage face imaging range calculation unit that is configured to calculate stage face imaging range data indicating a range of the stage face imaged by the X-ray detector at a position where an X-ray fluoroscopic image of the inspection target object is captured; and a dose distribution image display control unit that is configured to extract cumulative irradiation dose distribution data for a region corresponding to the stage face imaging range data from the cumulative irradiation dose distribution data as imaging range cumulative dose distribution data, and that is configured to display on the display device an image of the imaging range cumulative dose distribution data that corresponds to the imaging region of the X-ray fluoroscopic image. an X-ray source;
