A resolver includes a disc-shaped rotor provided with a detection coil pattern formed in flat shape and a stator formed in flat plate shape placed to concentrically fact the rotor in an axial direction and configured such that a planar first excitation coil pattern to which a cosine wave is supplied and a planar second excitation coil pattern to which a sine wave is supplied, the first and the second patterns being laminated. The first and second excitation coil patterns are placed to face the detection coil pattern. An insulation layer is formed with insulating coating material between the first and second excitation coil patterns.
