Abstract
To provide a measurement device which allows long-term accurate measurement of voltage without adversely affecting a device under test, by ensuring a predetermined level of resistance to ESD and reducing leakage current. A measurement device includes a probe needle for contacting a device under test, a first FET for detecting voltage of the device under test, and a protection circuit for protecting the first FET from static electricity. The protection circuit includes a second FET having an oxide semiconductor film as a channel formation region.
