Claim 0:
1. A resolver that detects an angle of rotation of a rotor relative to a stator, the resolver comprising:
a first coil group including a first exciting coil and a first detecting coil that have a multiplication factor of angle of n×(where n is a natural number equal to or greater than three), are placed coaxially with an axis of rotation of the rotor, and each have a ring shape; and
a second coil group including a second exciting coil and a second detecting coil that have a multiplication factor of angle of (n−1)×, are placed coaxially with the axis of rotation of the rotor, and each have a ring shape, wherein
the first coil group and the second coil group are provided at positions different in a radial direction from each other.
