A rotor capable of improving a torque of an electric motor and a mechanical strength of the rotor. The rotor is provided with a shaft, a plurality of rotor segments that are lined up in the axial direction, and a connecting structure that connects a conductor of a first rotor segment and a conductor of a second rotor segment, which is adjacent to the first rotor segment in the axial direction, and that mechanically connects the first rotor segment and the second rotor segment with each other.
