A hybrid excitation machine comprising a rotor having first and second rotor cores with an axial gap between; a stator placed radially outward of the rotor; and an exciting coil fixed to the stator placed in an air gap between the stator and rotor to protrude radially inward from the stator. In an axial direction, an axial end of a radially outer end of the first rotor core located on the second rotor core side and the second rotor core are positioned on opposite sides of an axial end of the exciting coil located on the first rotor core side, and an axial end of a radially outer end of the second rotor core located on the first rotor core side and the first rotor core are positioned on opposite sides of the axial end of the exciting coil located on the second rotor core side.
