PROBLEM TO BE SOLVED: To provide a flaw detection apparatus, for a small discoid work, especially a feed and ejection device, for the work, by which the fracture flaw on the surface of the small discoid work such as a shim can be inspected quickly and precisely. SOLUTION: In this flaw detection apparatus, the outer circumferential part of a discoid shim 1 which is supported horizontally in the inspection position of a flaw detection apparatus body X is sandwiched between two driving rollers 3 and one driven roller 4, and, while the shim 1 is being turned, fracture flaws on the upper and lower surface of the shim 1 are detected. The driven roller 4 is opened and closed by a first air cylinder 13. The shim 1 in the inspection position is transferred to the ejection position of an ejection chute 22 by two suction cups 29, and, at the same time, the shim 1 in the work feed position of a feed chute 21 is transferred to the inspection position.
