A rotation angle sensor comprises: a resolver stator including an excitation coil for receiving an excitation signal and a detection coil (a sine wave coil and a cosine wave coil) for outputting a detection signal; and a resolver rotor rotatably placed to face the stator. The resolver stator is formed on a stator flat plate. The resolver rotor is made of a flat-shaped rotor flat plate. The stator flat plate and the rotor flat plate are placed in parallel to face each other. The rotor flat plate is formed with a cutout.
