Simple measuring set-up was used to measure high-frequency impedance of superconducting Ti and NbN microstructures at low temperatures. The shift of resonance frequency below the temperature of superconducting transition compared to the normal state clearly indicates the increase of inductance of the system. The effect is interpreted as the impact of kinetic inductance originating from 'inertial' properties of Cooper pairs. Kinetic inductance of superconducting micro- and nanostructures should be taken into consideration for various cryoelectronic applications.
