PROBLEM TO BE SOLVED: To provide a survey signal transmission apparatus capable of guiding and transmitting surely a search signal to a survey object, even if the survey object has a small diameter. SOLUTION: The survey signal transmission apparatus 2 is used for outputting a survey signal for measuring a burying position of a buried survey object W from a survey signal output part 3, guiding and transmitting the search signal to the survey object W, and thereby receiving an alternating field generated from the survey object W on the ground surface to measure the burying position of the survey object W. The apparatus includes a transmission coil 4 for guiding and transmitting the search signal to the survey object W in the close state to a part exposed from the ground of the survey object W, an extensible/contractible support rod 9 for supporting a body part 7 with the built-in transmission coil 4, and a hooking body 10 for allowing a band 12 fixing the part exposed from the underground of the survey object W to hold the body part 7.
