A rotor position sensor for an electric motor of an electric power steering apparatus for assisting steering of a motor vehicle is configured to generate a sensor signal which represents the rotor position of the electric motor's rotor. The rotor position sensor has at least one sensor unit that generates electrical signals having different phases in accordance with rotation of a rotary shaft of the electric motor that is a sensing target, wherein the rotor position sensor includes two redundant sensor units wherein each of the sensor units includes tunnel magnetoresistive elements.
