A measuring instrument for contactless detection of an angle of rotation comprises a carrier plate ( 52 ) consisting of a magnetically soft material that serves as a rotor. The stator of the sensor comprises at least two parts, the ends ( 18 and 17 ) of which terminate in two planes. The measuring gap (M 1 ) containing an element ( 20 ) that is sensitive to a magnetic field is located between the ends ( 18, 17 ). Due to the fact that the ends ( 17, 18 ) of the two stator parts ( 13, 14 ) terminate in different planes, the measuring element ( 20 ) can be situated in a very small measuring gap (M 1 ) in which the magnetic flux of the magnet ( 5 ) can be concentrated.
