摘要 A rotor (120) that can reduce the used amount of resin for securing a permanent magnet (123) is provided. The rotor (120) includes a rotor core (125) provided fixedly to a rotation shaft (110) and having a magnet insertion hole (126) extending in an axial direction formed therein, a permanent magnet (123) embedded in the magnet insertion hole (126) and extending in the axial direction and extending in a direction inclined relative to a radial direction of the rotor core (125), and a resin layer (137) that secures the permanent magnet (123) to the rotor core (125). The resin layer (137) covers a surface of the permanent magnet (123) and is in contact with an inner surface of the magnet insertion hole (126). A hollow space (132) extending in the axial direction is left in the magnet insertion hole (126) at an inner side in the radial direction relative to the permanent magnet (123). Part of the inner surface of the magnet insertion hole (126) is exposed to the hollow space (132).
