| description | The present invention provides an eddy current flaw detection device that sufficiently removes noise from a detection signal. A magnetic field is applied to a test object by a magnetic-field forming magnet. The magnetic flux density of a magnetic field generated by the magnetic-field forming magnet is set at a value in a predetermined range according to a distance between the magnetic-field forming magnet and a detection surface and the thickness of the test object. |
