An object of the present invention is to provide a dynamic characteristic measurement device capable of accurately measuring dynamic vibration characteristics of a rubber isolator and the like in a high-frequency vibration range. A dynamic characteristic measurement device according to the present invention includes a base, a support part that is placed above the base so as to be capable of floating via an air spring, an electrodynamic vibrator that is provided on the base side of an object under test mounted between the base and the support part and vibrates the object under test, and a load washer that is provided on the support part side of the object under test and measures a dynamic load applied to the object under test. Here, a crosshead of the support part is shaped such that a resonant frequency is at least 3 kHz.
