Zusammenfassung:An electronic device inspection apparatus of the present application comprises an inspection table for positioning and holding an electrode disposed on a semiconductor device , a contact element that is formed of a shape memory alloy in a long and thin plate shape and has a base part fixed to the inspection table and a variable part formed in a shape of a spiral at a first temperature and being developed from the spiral at a second temperature; and a measurement circuitry for measuring the semiconductor device by conducting a current to flow into the electrode via the contact element. The axis of the spiral of the variable part is parallel to the electrode face of the positioned electrode and a contact region is formed along a longitudinal direction between the variable part and the positioned electrode at the second temperature.
