A detection apparatus for detecting foreign substances or defective goods, with which it is easy to accomplish inspection even if the inspection objects have a shape that tends to allow rolling, comprises: transparent members 11 and 12, partitions 21 and 22, a supplying unit 30, cameras 41 and 42, a control unit 50. A removing apparatus 1, which includes such detection apparatus, comprises a suction controller 60 and suction nozzles 61 to 68. While the partitions 21, 22 move around, inspection objects A are each put in each cell of the partitions 21, 22, and are photographed by the cameras 41 and 42, from above and below the transparent members 11, 12, respectively. The images obtained by such photographing are analyzed, and foreign substances or defective goods mingling in the inspection objects A are detected. The foreign substances or defective goods are separated from the conforming goods by selectively sucking the inspection objects A with the suction nozzles 61 to 64.
