PROBLEM TO BE SOLVED: To provide a method of manufacturing split permanent magnets that facilitates forming insulating layers among each permanent magnet piece, even when the number of the permanent magnet pieces is increased, and to provide an electric motor using the split permanent magnets. SOLUTION: A positioning sheet 3 having an elasticity is stuck on joint surfaces 22 perpendicular to the split boundary surfaces 21 of each permanent magnet piece 2 and each permanent magnet piece 2 is connected, and the whole is curved under the state joining the permanent magnet pieces 2 with the positioning sheet 3. Openings 23 are formed among the permanent magnet pieces 2, and the openings 23 are filled with liquefied insulating materials 4. Accordingly, a series of the filling works of the liquefied insulating materials 4 are facilitated, thereby the insulating layers I can be formed easily among the permanent magnet pieces 2 and 2 even when the number of the permanent magnet pieces 2 is increased.
