Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sensor for detecting a buried object of complex-type enhancing detection sensitivity of a magnetic sensor. SOLUTION: The sensor 10 includes a magnetic sensor 12 and a radio-frequency sensor 14, consisting of a receiving section 16 and a transmitting section 18, preparing a plurality of antenna elements constituting the radio frequency sensor 14 on the periphery of the receiving section 16 and moreover, preparing the transmitting section 18 on a periphery of the radio-frequency sensor 14 centered on the receiving section 16. The receiving section 16 is made into a circular form by combining a pair of semicircular coils 20 symmetrically and forms the directions of coil pattern of the coil 20 which is to be mutually reversed.
