The vibration isolation device of the present invention includes a first position feedback control system including a reference body system that is fixed to an object to be isolated from vibration and includes a reference body; a first driving unit that drives the object with respect to a base; and a first compensator that calculates a command value to the first driving unit based on position information obtained from the reference body system. Also, the reference body system includes a second position feedback control system including a second driving unit that drives the reference body with respect to the object; a first measuring unit that measures the position of the reference body relative to the object; and a second compensator that calculates a command value to the second driving unit based on position information obtained from the first measuring unit. Here, the second compensator is a PD compensator.
