PROBLEM TO BE SOLVED: To measure local electric characteristics of a device having a fine structure for detecting a defect. SOLUTION: While observing with a scanning electron microscope, a plurality of probes 1, 2, 3 and 4 each having a sharp tip are made to approach sample electrodes 5, 6, 7 and 8, respectively, and made to come into contact with them completely until a contact current saturates by the use of probe moving mechanisms 14, 15, 16 and 17 under the control of a probe movement control circuit 18. After all of the probes used for measurement are made to come into contact with them, the current-voltage characteristics between probes are measured by the use of an electric characteristic measuring circuit 19 and thus the local electric characteristics of an element are obtained.
