A flat rotary electric machine to be mounted in a vehicle engine includes an annular stator core with a plurality of teeth and an armature winding and a field unit including a gutter-like field core having a pair of coaxial cylindrical core members. A plurality of permanent magnets are disposed on the cylindrical core members and an annular field coil disposed between the cylindrical core members. Each of the cylindrical core members has a plurality of magnet-conductive salient magnetic poles disposed between the permanent magnets, the permanent magnets are magnetized so that all the magnetic flux thereof can cross the stator through the teeth in the same direction.
