PROBLEM TO BE SOLVED: To provide an electric motor having a rotor which can be easily manufactured without impairing the performance of the electric motor even in a small size by using a rotor core as a magnet stop and to provide an apparatus which carries the same. SOLUTION: The magnet stopping core is provided at the axial end of the rotor core. The magnet stop, for which a permanent magnet 17 may not be axially projected from the rotor, is constituted by deforming the hole 12 for inserting the permanent magnet of the magnet stopping core by the length part of the difference or less between an axial length of the rotor and the axial length of the permanent magnet 14 shorter than the axial length of the rotor.
