PROBLEM TO BE SOLVED: To prevent a magnetic resistance between a stator and a rotor from changing depending on the position of the rotor. SOLUTION: The rotary electric machine is configured so that the thickness direction of a plurality of magnetic plates 121a-121o constituting the stator 120 follows the rotating direction of the rotor 110, and the regions of the plurality of magnetic plates 121a-121s which oppose at least permanent magnets 115a-115j are disposed with a substantially equal spacing in the rotating direction of the rotor 110. Accordingly, even if the rotor 110 rotates to cause a change in the positional relation between the permanent magnets 115a-115j constituting the magnetic poles 115, 116 and the magnetic plates 121a-121o constituting the core 121 of the stator 120, fluxes to be imposed on the respective magnetic plates 121a-121o from the permanent magnets 115a-115j become substantially the same. Thus, the magnetic resistance between the magnetic plates 115, 116 and the core 121 of the stator 120 is substantially the same (as a whole), irrespective of the position of the rotor 110.
