In the present disclosure, there is provided a permeability measurement jig including a first waveguide, wherein a signal line of the first waveguide comprises an excited magnetic part at one end side, and a magnetic field is generated at the excited magnetic part by an excitation signal, and a second waveguide, wherein a signal line of the second waveguide comprises a detection part at one end side, a detection signal is induced at the detection part due to an action of the magnetic field generated at the excited magnetic part to a measurement sample, and the detection part is placed on the excited magnetic part to face the excited magnetic part at a predetermined distance. A permeability measurement device having the permeability measurement jig and a permeability measurement method are disclosed.
