PROBLEM TO BE SOLVED: To provide an X-ray foreign object inspection apparatus which can clearly display shapes of foreign objects in objects under inspection being conveyed on a conveying path by acquiring radioscopic images viewed from an oblique angle.;SOLUTION: Shoes under inspection are irradiated with fan-beam X-rays 1 from an X-ray source 30, and the X-rays that passes through the shoes are detected by an X-ray detector to obtain a radioscopic image. The X-ray source 30 and the X-ray detector are positioned to have a conveying path in between. The X-ray source 30 is set up such that an X-ray central plane 1a that cuts through a center point of the fan-beam X-rays 1 in a thickness direction thereof intersects with a conveyor reference plane 23a on the conveying path at an angle. The X-ray detector comprises a plurality of X-ray line sensors which are positioned along an L-shaped reference line A such that all of many X-ray detection elements (of each X-ray line sensors) intersect with the X-ray central plane 1a of the fan-beam X-rays 1.;COPYRIGHT: (C)2015,JPO&INPIT
