<P>PROBLEM TO BE SOLVED: To provide a magnetic resolver, the yield of which is high when manufacturing a plurality of substrates from the substrate material. <P>SOLUTION: The magnetic resolver 10 comprises the annulus stator part provided with protruded cores 22, the annulus coil substrate 30 formed by the thin film coil pattern 34 provided around the protruding cores, the rotor part 40 provided upon the stator part across the coil substrate with the over lapping areas with the protruding cores varying depending on the rotation angle in the vertical view. The annulus coil substrates are characteristically composed of each of substrate pieces (301, 302, and 303) divided into a plurality of pieces of substrates. <P>COPYRIGHT: (C)2008,JPO&INPIT |
