A foreign matter inspection apparatus, which enables more sufficient detection of foreign matter included in inspection objects, comprises: (1) a transparent drum having a cylindrical shape turning around a horizontal central axis; (2) an object supplying unit for supplying inspection objects to such a given region on the surface of the drum as will not cause the inspection objects to slide; (3) a first image capturing unit for imaging the inspection objects placed on a first imaging area included in the given region, such imaging being done from outside the drum; (4) a second image capturing unit for imaging the inspection objects placed on a second imaging area included in the given region, such imaging being done from inside the drum; and (5) an analyzing unit for analyzing existence/nonexistence of any foreign matter mingling with the inspection objects, such analysis being done on the basis of images captured by the first image capturing unit and the second image capturing unit. |
