PROBLEM TO BE SOLVED: To provide a friction coefficient measuring instrument for measuring a true friction coefficient of a specimen wherein the Coulomb's law does not hold in an interface and a friction coefficient depends on a relative speed between an ideal surface and a rough surface. SOLUTION: This friction coefficient measuring instrument includes a movable stand 11 comprising a contact part 21 contacting with a part of the specimen 91, a control means 12 for moving the movable stand 11 with the specimen 91 kept in contact with the contact part 21, a connection means 13 connected to the specimen 91 to convey a force caused by friction between the specimen 91 and the contact part 21, a transducer 14 converting the force conveyed by the connection means 13 into an electric signal, and a measuring means 15 for sampling the electric signal from the transducer 14 in a prescribed cycle.
