PROBLEM TO BE SOLVED: To provide a rotor of a rotating electric machine which enhances efficiency by reducing torque ripple, iron loss and higher harmonics and suppress generation of resistance due to rotation of the rotor, and to provide a rotating electric machine. SOLUTION: The rotor of a rotating electric machine comprises a rotor core 11, a plurality of magnet insertion holes 13 provided in the outer circumferential part of the rotor core 11 at constant intervals in the circumferential direction, permanent magnets 14 for magnetic pole formation inserted into the respective magnet insertion holes 13 and an outer circumferential hole 19 provided in the outer circumferential part of the rotor core 11. The outer circumferential hole 19 in the circumferential direction of the rotor core 11 ranges from a position of a predetermined angle for the d axis (electrical angle ϕ<SB>1</SB>for the d axis) to a position of a predetermined angle for the d axis (electrical angle ϕ<SB>2</SB>for the d axis), i.e., near the chip portion 18 existing on the side separating from the d axis (q axis side).
