A permanent-magnet-embedded electric motor includes a stator core including a yoke and a plurality of teeth, a rotor core including a plurality of magnet insertion holes, and a plurality of permanent magnets respectively inserted into the magnet insertion holes, each being arranged with a lateral direction set in a radial direction of the rotor core and with a longitudinal direction set in a direction orthogonal to the radial direction. When a width of base sections of the teeth is represented as S1, a width of a distal end sections of the teeth is represented as S2, a width of the permanent magnets in the longitudinal direction is represented as R1, and a width of the magnet insertion holes in an extension direction thereof is represented as R2, relations of S1≤R1
