An angle sensor includes a sensor rotor formed with a planar coil and a sensor stator placed to face the sensor rotor with a gap therefrom and formed with a planar coil. The planar coil of the sensor stator includes an SIN phase coil and a COS phase coil each having an annular ring shape, and a rotary transformer coil placed radially inside of a region where both the coils are provided. The rotary transformer coil includes two connecting wires to connect to an external circuit, the two connecting wires being arranged to extend across the coils. The two connecting wires are arranged one above the other in their portions that extend across the coils while an insulating film is interposed between the connecting wires. |
