An embodiment relates to a sensing device comprising: a stator; and a rotor, at least a part of which is arranged on the stator. The stator comprises a stator holder, a stator body coupled to the stator holder, and a first stator tooth and a second stator tooth arranged on the stator body. The rotor comprises a rotor holder, a rotor body coupled to the rotor holder, and a magnet coupled to the rotor body. The first stator tooth comprises a first body and multiple first teeth connected to the first body and spaced apart from each other. The second stator tooth comprises a second body and multiple second teeth connected to the second body and spaced apart from each other. The multiple first teeth and the multiple second teeth overlap in the radial direction. Accordingly, the sensing device can prevent or minimize magnetic-field interference resulting from an external magnetic field generated outside during torque measurement.
