Claim 5:
6. The rotating electric machine according to claim 1,
wherein the radially-outer side surface of the rotor core has recessed portions formed at two spots corresponding to the second q-axis magnetic path, respectively,
wherein one of the recessed portions formed at the two spots is set as a first recessed portion, and the other of the recessed portions formed at the two spots is set as a second recessed portion, and
wherein the rotating electric machine satisfies the following expression:

θ2=2π×n2÷{P×(2m2−1)} [rad], where:

θ2 represents an angle between a straight line passing through a widthwise center of the first recessed portion and a radial center point of the rotor core and a straight line passing through a widthwise center of the second recessed portion and the radial center point of the rotor core;
m2 represents a natural number; and
n2 represents a natural number smaller than m2.
