Abstract: A method for measuring electron mobility according to the present invention, which is performed by an apparatus comprising a chamber forming a sealed space, an electron gun provided in the chamber, and a metal sample disposed opposite to the electron gun in the sealed space, comprises: an electron irradiation step of irradiating the metal sample with electrons by the electron gun; a sample current measurement step of applying a voltage to the metal sample to measure a sample current obtained in the metal sample according to the applied voltage; a secondary electron current calculation step of calculating a secondary electron current through the measured sample current; and an effective incident current definition step of defining the sum of the measured sample current and the calculated secondary electron current as an effective incident current.
