PROBLEM TO BE SOLVED: To provide a non-pressure-bonded part detecting device for a steel plate simplified in the structure of the detecting device itself. SOLUTION: This non-pressure-bonded part detecting device for a steel plate is equipped with a probe 21 for transmitting and receiving ultra short waves, a reflector 22 for reflecting ultra short waves transmitted from the probe 21 and having passed through an inspected material T, to the probe 21 and a non-pressure-bonded part detecting means 12 for detecting a non-pressure-bonded part Tc based on the intensity of reflection waves reflected by the reflector 22 and received by the probe 21. |
