There is provided a rotary eddy current flaw detection probe device in which a plurality of ˜-shaped eddy current flaw detection probes are attached in a rotating disc, so as to be capable of detecting flaws in all directions regardless of the flaw direction. The four ˜-shaped eddy current testing probes P11 to P22 are arranged around the rotation center Ds 1 of a rotating disc 111, and are embedded in the rotating disc 111. The coil planes of detector coils Ds11 to Ds22 of the eddy current testing probes P11 to P22 are parallel with each other, and are perpendicular to the rotation plane of the rotating disc 111. The coil planes of the detector coils incline at an angle ¸ relative to a line Y passing through the centers Ps11 and Ps12 of the eddy current testing probes P11 and P12. The detector coils Dc11 and Dc12 are cumulatively connected to each other, and the detector coils Dc21 and Dc22 are differentially connected to each other. |
