PROBLEM TO BE SOLVED: To provide an instrument and a method for measuring a magnetic characteristic of an annular sample, not necessary to spend a long time for preparation of measurement in every time thereof, and capable of measuring an accurate magnetic characteristic, even when using the annular sample in conformity with an actual using shape as a measuring object. SOLUTION: This instrument for measuring the magnetic characteristic has: a plurality of sample storage parts for storing each of a plurality of sample pieces comprising the annular measuring object divided along a circumferential direction, by a slide; a connection part for connecting magnetically each space between the plurality of sample pieces stored in the sample storage parts in order to form a closed magnetic path corresponding to the measuring object; and an excitation coil formed woundly in an each outer circumference of the sample storage parts, and for exciting each of the plurality of sample pieces forming the closed magnetic path, and a detecting coil for detecting an excitation magnetic flux in the closed magnetic path.
