PROBLEM TO BE SOLVED: To provide an outer rotor permanent magnet motor that easily brings a magnetic flux density into a sine curve shape without need for increasing the thickness of a permanent magnet in increasing the magnetic force of a magnetic pole. SOLUTION: A reversed T-shape hole 14 is formed on a portion 13 having a magnetic pole of a rotor core 8, and in the hole 14, two permanent magnets 9a, 9b having different widths are stacked.
