A skew angle measurement method of a skew magnet using magnetic flux is provided to inspect the accurate formation of a magnetic skew by the skew magnet magnetically by using a difference of a phase angle of a magnetic flux quantity of the skew magnet. A skew angle measurement method of a skew magnet(120) using magnetic flux includes the steps of: measuring a magnetic flux amount discharged by the skew magnet as a rotor(100) rotates on the basis of a reference point of a magnetic flux measurement sensor(200); measuring the magnetic flux quantity discharged by the skew magnet as the rotor rotates at a position where the magnetic flux measurement sensor moves along an axial direction of the rotor; measuring a difference of a phase angle generated between the magnetic flux quantity discharged by the skew magnet; measuring a movement distance of the magnetic flux measurement sensor moving along the axial direction of the rotor; and determining a skew angle with respect to an axial length of the skew magnet by using a ratio of the reference point for the movement distance of the magnetic flux measurement sensor and the difference of the phase angle of the magnetic flux quantity.
