PROBLEM TO BE SOLVED: To improve an efficiency of heat exchange with a ground in an underground heat exchanger used for heat collection from an underground and heat radiation to the underground. SOLUTION: In an embedding method of the underground heat exchanger 1, a long pile 13 for embedding is formed in the underground G, the pipe-like underground heat exchanger 1 which subjects a heat medium L1 to heat exchange with the ground in a process of passage in an outward or a homeward route is inserted into the long pile 13 for embedding in a state in which a heat source inlet 10 and a heat source outlet 11 face to a surface of earth, and in this insertion state the pile 13 for embedding is filled with a solidification type liquid filler S. In this method, at filling of the liquid filler S, vibration is applied to the underground heat exchanger 1 by a vibration generator 18 at a surface opening part of the pile 13 for embedding whereby the vibration is transmitted to the filler S inside the pile 13 for embedding via the underground heat exchanger 1.
