In this rotor (101), which has permanent magnets (105) inserted in a rotor core (102), main body sections (117) of magnetic shield sections (107) are formed in contact with the q-axis-side end faces (105q) of each permanent magnet (105). In addition, an extension section (127) for each magnetic shield section (107) is formed positioned more toward the outer periphery than the outer-periphery-side pole face (105ou) of the permanent magnet (105) and between the d-axis and the q-axis at an end face of the rotor core (102). Each extension section (127) is configured so as to gradually approach the outer periphery of the rotor core (102) while extending from the outer-periphery-side end of the main body section (117) from the q-axis side to the d-axis side, and then gradually move away from the outer periphery of the rotor core (102) while extending from the q-axis side to the d-axis side. |
