Abstract
An angle sensor includes a sensor rotor formed with a planar coil and a sensor stator including a multi-X type planar coil placed to face a surface of the sensor rotor. On a stator substrate of the sensor stator are provided forward-direction planar coils and reverse-direction planar coils, and positive and negative terminals adjacently arranged. The forward-direction and reverse-direction planar coils are connected in series through connecting wires. One of both ends of the series-connected planar coils is connected to the positive terminal through the wire and the other end is connected to the negative terminal through the wire. The wires are arranged along arrangement of the series-connected planar coils but in a range less than a full circle of the arrangement. A turn-back connecting wire extending from one end of the series of planar coils is arranged along the other connecting wire and connected to the negative terminal.
