PROBLEM TO BE SOLVED: To provide a flaw detection method and flaw detector of a metallic machine component that allows automated and unmanned defect determining operation of a machine component and can achieve high efficiency and cost reduction of flaw detection, by automating the scanning of a flaw detection probe to the machine component by incorporating a flaw detection mechanism into an existing NC unit. SOLUTION: The flaw detector of the metallic machine component has a flaw detecting means including a flaw detection probe 2, a rotation unit 3 for rotatably supporting the flaw detection probe 2 and rotating and driving it, and an image processing apparatus to be connected to the rotation unit 3. The flaw detection probe 2 can be moved along the machine component 11 when the rotation unit 3 is installed in a slide section 7 of a column 6 of the NC unit 5 and moves with the slide section 7 and/or when the machine component 11 moves with a table 8 of the NC unit for chucking it.
