A sheet coil type is provided in which a detection coil of two phases is disposed at a stator section and structured such that a coil of sine phase a coil of cosine phase are circumferentially arranged alternately on the same plane, wherein the distance between an excitation coil at a rotor section and the coil of sine phase at the stator section is identical to the distance between the excitation coil at the rotor section and the coil of cosine phase at the stator section, whereby the difference in amplitude between at a sine phase output and at a cosine phase output is eliminated. |
