PURPOSE: An instantaneous separating device of a target and a temporary structure using an explosive bolt is provided to reduce costs for dismantling a temporary structure since the load of the temporary structure moves back and is automatically separated. CONSTITUTION: An instantaneous separating device of a target and a temporary structure using an explosive bolt comprises a target(1), a coupling unit and explosive bolts(6a,6b). The coupling unit is installed as an overground structure to be able to change an angle and supports the target. The explosive bolts are installed between a hydraulic cylinder and a fixed body, which make the temporary structure stand or lie and are installed on one end of a link supporting load. If a worker operates an ignition switch to separate the target from the temporary structure, a control unit first explodes the explosive bolts and then explodes the explosive bolts between the fixed body and one end of the link to move back the load of the temporary structure.
