A field coil type rotating electric machine includes a field coil having first and second windings connected in series with each other, a rotor having main poles on which the first and second windings are wound, and a stator having a stator coil comprised of phase windings to which harmonic currents are respectively supplied to induce field current in the field coil. In the rotor, there are formed a series resonant circuit including the first winding and a capacitor and a parallel resonant circuit including the second winding and the capacitor. The first winding is radially located closer to the stator than the second winding is. Moreover, N1
