An X-ray inspection apparatus includes a scanning X-ray source for emitting an X-ray, an X-ray detector drive unit having a plurality of X-ray detectors mounted thereon and being capable of independently driving the plurality of X-ray detectors, and an image acquisition control mechanism for controlling the X-ray detector drive unit and acquisition of image data from the X-ray detectors. The scanning X-ray source emits an X-ray by moving an X-ray focal point position of the X-ray source to each of originating point positions of X-ray emission, which are set for the X-ray detectors such that X-rays are transmitted through a plurality of prescribed inspection areas of an inspection object and enter the X-ray detectors. Image pickup by the X-ray detector and movement of another X-ray detector are concurrently performed in an alternate manner. The image acquisition control mechanism acquires image data, and an operation unit reconstructs an image.
