CONSTITUTION:A probe 10 has a detection coil 02 disposed close to the center at the inner side of an exciting coil 01. The position of the detection coil 02 is so adjusted that excellent detectability can be obtained. Both the exciting coil 01 and the detection coil 02 are connected to a flow detector via a connection cable 130. An electromagnetic field is generated by the exciting coil 01, and a magnetic field affected by eddy current within an inspected metal 110 is detected by the detection coil 02, so that voltage is thereby induced. The detection coil 02 is almost free from a magnetic field acting on the surface section of the inspected metal 110 out of magnetic fields generated by the exciting coil 01, but it is affected only by the change of a magnetic field acting on the back face section of the inspected metal 110. Therefore, a signal caused by abnormalities such as defects and the like existing in the back face section of the inspected metal, is thereby amplified respectively.
