Four-terminal measuring device that uses nanotube terminals

A four-terminal measuring device that uses nanotube terminals wherein said four-terminal measuring device is comprised of:

• two current terminals which cause a constant current to flow from a constant-current power supply to an object under test, and
• two voltage terminals which measure a voltage across both ends of said object under test, and wherein
• a nanotube terminal comprising a base end portion of a nanotube fastened on a metal film of a holder of a cantilever by a coating film or thermal fusion so that a tip end portion of said nanotube protrudes from said holder and an electrode film of said cantilever electrically connected to said metal film so that said nanotube is electrically connected to said electrode film, and
• said nanotube terminals are connected to at least two voltage terminals so that a voltage across said tip end portions of said nanotubes is measured.
