PROBLEM TO BE SOLVED: To provide a marker surveying device for preventing the occurrence of erroneous detection that a marker being a survey object has been detected even when a marker that is not a survey object exists within a close range.SOLUTION: A marker surveying device 111 includes: an antenna 112 constituted by arranging a coil used in common for transmission and reception inside a disk shape housing; and a device body 113. The device body 113 includes: a transmission circuit 114 for transmitting a transmission signal of a frequency being the same as a resonance frequency of a marker 61, to the antenna 112; a reception circuit 115 for receiving a response signal from the antenna 112, passing the signal through a band-pass filter 122, and extracting a position and depth of the marker 61; and a signal switching circuit 120 for performing switching between the transmission circuit 114 and the reception circuit 115. An amplitude limit circuit 124 is formed inside the band-pass filter 122.
