PROBLEM TO BE SOLVED: To provide a heat exchanger utilizing geothermal heat, which can efficiently utilize geothermal heat.SOLUTION: A heat exchanger includes a pipe 2 through which heat medium liquid flows, the pipe comprising: a heat collection pipe part 5 buried in the ground; and a heat absorption/radiation pipe part 6 capable of radiating heat in a region where heat should be radiated, and absorbing heat in a region where heat should be absorbed. A pump 4 configured to circulate heat medium liquid through the pipe 2 is interposed in the pipe 2. For a highly heat-conductive part 7 covering the heat collection pipe part 5, an internal cavity part 10 formed inside a conductive part 9 comprising a mixture of silica rock and silica sand is filled with water-containing filler 11 comprising antiseptic konjak 13, and the water-containing filler is accumulated at the internal cavity part.SELECTED DRAWING: Figure 1 【課題】地中熱を効率的に活用し得る地中熱利用の熱交換装置を提供する。【解決手段】熱媒液が内部を流れる管体２を、地中に埋設される採熱管部５と、放熱されるべき領域において放熱し又は吸熱されるべき領域において吸熱し得る吸放熱管部６を具えたものとする。管体２内で熱媒液を循環させるポンプ４を管体２に介在させる。採熱管部５を覆う高熱伝導部７は、珪石及び珪砂の混合物からなる伝導部９の内部に形成されている内部空隙部１０に、防腐性蒟蒻１３からなる含水充填材１１が充填され、該含水充填材が該内部空隙部に留まっている。【選択図】図１
