PROBLEM TO BE SOLVED: To provide an electromagnetic driving unit which reconciles downsizing and energy-saving. SOLUTION: This electromagnetic driving unit has a permanent magnet 3 which is insert-molded in a position apart in its radial direction from the center to a rotatable driven member 2, stators 5 and 6 which are arranged to face the side of one magnetizing part (N pole) of a permanent magnet, and an electromagnetic coil 7 which energizes the stator yoke. This makes the magnetic attraction and repulsion arising between the side of one magnetizing part of the permanent magnet and the stator yoke work on the above permanent magnet thereby rotating the driven member where the permanent magnet is insert-molded.
