A method for measuring vibration characteristic of a cantilever is proposed in this disclosure. The method includes: measuring vibration amplitude V of a cantilever installed in a scanning probe microscope when vibration with a resonant frequency f1 (Hz) is applied to the cantilever; obtaining a time Th (second) when the vibration amplitude V is equal to or more than 0.90 of a stationary amplitude V0; and calculating a Q value by using the following Expression: Q value=f1×Th.
