PROBLEM TO BE SOLVED: To provide a rotor of a permanent magnet motor, capable of ensuring a distance between different polarity magnets adjacent in an axial direction without requiring chamfering processing for magnets. SOLUTION: The rotor is used for the permanent magnet motor having a plurality of permanent magnets (20, 30) which are disposed in an axial direction and sequentially skewed in a circumferential direction. The rotor has intermediate magnet portions (40, 50) between the permanent magnets (20, 30) of adjacent upper and lower stages. The intermediate magnet portions (40, 50) are configured so that the edge line of the skew direction side are positioned on the extension of the edge lines of the skew direction side of the upper stage permanent magnets (20, 30), and the edge lines different from the skew direction side are positioned on the extension of the edge lines different from the skew direction side of the lower stage permanent magnets (20, 30).
