探知装置。[Scope of claim for utility model registration] Detection that detects the position of a side hole from above the ground surface using the received signal obtained by receiving a radio signal transmitted from a transmitting antenna inside the side hole while moving a receiving antenna on the ground surface. The apparatus includes: means for transmitting a reference signal by applying a reference signal to the transmitting antenna; means for measuring a phase difference between the received signal and the reference signal; and a receiving antenna position at which a minimum value of the phase difference is obtained. A side hole detecting device comprising: detecting means for detecting or displaying as the position of the side hole.
