A brushless winding field rotational electric machine 10 includes: a stator 3, which is held to a case 5, including an alternating-current coil 14 configured to generate a rotation magnetic field by alternating current; a field core 6, which is held to the case 5, including a field coil 2 to be excited by direct current; and a rotor 1 disposed on an outer periphery of a rotation member 4 and rotatably held about a rotational axis 7 thereof relative to the stator 3 and the field coil 2. The field coil 2 includes a plurality of coil winding layers 201-204 stacked in a radial direction of the rotational axis 7. A cross-sectional area along an axial direction of the rotational axis 7, of a coil winding layer 204 closest to the rotational axis 7 in the radial direction of the rotational axis 7 is smaller than a cross-sectional area along the axial direction of the rotational axis 7, of a coil winding layer 201 farthest from the rotational axis 7 in the radial direction of the rotational axis 7.
