PURPOSE: A seismic isolation device is provided to implement seismic isolation performance regardless of the kind of an object by modularizing a plurality of seismic isolation members. CONSTITUTION: A support stand(10) is a steel plate. A plurality of first seismic isolation members(20) is arranged on the support stand to absorb the vibration energy of an earthquake. One or more second seismic isolation members(30) are arranged in the center of the support stand to damp the vibration energy of the earthquake. The second seismic isolation member comprises a lead post. A support unit(40) faces the support stand between the first and second seismic isolation members. The support stand supports the object to be protected.
