Claim:
1. A rotor for a rotating electric machine, the rotor comprising: a core body having a magnet disposed on the core body at a position corresponding to the first polar portion or the second polar portion, wherein the first through-hole has a first arc-shaped surface on an outer side in the radial direction, and the first arc-shaped surface of the first through-hole has a first curvature radius being centered at a center axis of the core body coincident with a shaft axis, the first polar portion has a second arc-shaped surface on an outer side in the radial direction, and the second arc-shaped surface of the first polar portion has a second curvature radius being centered at a first point, the second polar portion has a third arc-shaped surface on an outer side in the radial direction, and the third arc-shaped surface of the second polar portion has a third curvature radius being centered at a second point, the first curvature radius of the arc-shaped surface of the first through-hole is larger than or equal to the second curvature radius of the arc-shaped surface of the first polar portion, the first curvature radius of the arc-shaped surface of the first through-hole is larger than or equal to the third curvature radius of the arc-shaped surface of the second polar portion, the first point is located between the center axis and the second arc-shaped surface of the first polar portion in the radial direction, such that the first point and the center axis are not coincident, and the second point is located between the center axis and the third arc-shaped surface of the second polar portion in the radial direction, such that the second point and the center axis are not coincident.
