ABSTRACT:
A rotational angle detecting device has a pair of permanent magnets and an angle sensor. Electrical connecting terminals are connected to the angle sensor and further connected to conductors. The conductors have seconds ends opposite to the first ends and serving as connector terminals of the connector. In one embodiment, the rotational angle detecting device includes a first resin-molded portion and a second resin-molded portion. The first resin-molded portion includes at least the electrical connecting terminals, a part of the angle sensor and the first ends of the conductors embedded within a first resin. The second resin-molded portion includes portions of the conductors embedded within a second resin. In another embodiment, capacitors are connected to the connector conductors. The angle sensor has a magnetic detecting element positioned substantially perpendicularly to the rotational axis of the rotary section. The connector conductors have parallel portions extending substantially parallel to the rotational axis. A portion of the angle sensor assembly extending from the angle sensor to the parallel portions of the connector conductors has a substantially L-shaped configuration. The capacitor(s) is disposed on the same side as the magnetic detecting element with respect to the L-shaped portion.
