PURPOSE: A heat utilization system using storage heat of underground bedrock is provided to the storage and utilization of heat by adding the additives of high thermal conductivity into cement and bentonite fillers. CONSTITUTION: A heat utilization system(200) using storage heat of underground bedrock(10) comprises a circulation pipeline(16) of a closed loop for storing heat, an endothermic heat exchanger(20), a heat storage circulating pump(30), a heat radiating circulation pump(42), and a heat radiating heat exchanger(46). The circulation pipeline of a closed loop for storing heat is connected to a heat medium flow path, and transports a first heat medium. The endothermic heat exchanger heat-exchanges solar heat or waste heat collected in a solar heat collection system(100) with the first heat medium. The heat storage circulating pump forcibly circulates the first heat medium through the heat medium flow path the by turns. The heat radiating circulation pump forcibly circulates a second heat medium, which absorbs the heat of the underground bedrock. The heat radiating heat exchanger discharges the absorbed heat of the second heat medium to the heat utilization system.
