Abstract
A rotating electric machine includes a stator and a rotor. The rotor includes a rotor core, an axial end part, and a rotor magnet inserted into an insertion hole formed so as to pass through the rotor core. The axial end part has a recessed portion. The rotor magnet includes a first side surface and a second side surface. The first side surface is fixed to a first inner wall surface of the insertion hole. In a cross section perpendicular to the axial direction, a width of the first inner wall surface is larger than a width of the first side surface. The second side surface is fixed to a second inner wall surface of the recessed portion. In the cross section perpendicular to the axial direction, a width of the second inner wall surface is larger than a width of the second side surface.
