Claim 4:
5. The rotating electric machine according to claim 1,
wherein, in a part of the rotor core between the magnet insertion hole group and the magnetic slit, a first q-axis magnetic path is formed,
wherein, in a part of the rotor core between a pair of the magnet insertion holes adjacent to each other, an inter-magnet magnetic path is formed, and
wherein the following expression is satisfied:

d1>Bmag/Bs×W1−0.5×W2,

where d1 represents a widthwise dimension of a first q-axis magnetic path exit part which is a radially outer part of the first q-axis magnetic path, W1 represents a dimension of each of the plurality of permanent magnets in a direction perpendicular to a magnetization direction of each of the plurality of permanent magnets when viewed in an axial direction, W2 represents a widthwise dimension of the inter-magnet magnetic path, Bmag represents a magnetic flux density of each of the plurality of permanent magnets, and Bs represents a saturation magnetic flux density of the rotor core.
