Beschreibung
Zusammenfassung:	A rotation detector component detects a rotational state of a rotor and sends a rotational detection signal. A signal transmission component is electrically connected with a lead frame of the rotation detector component to transmit the rotational detection signal to an external device. A body portion holds the rotation detector component and a part of the signal transmission component. The body portion is integrally molded of a first resin to cover a joint portion between the lead frame and the signal transmission component, the rotation detector component, and a part of the signal transmission component. A part of the rotation detector component forms an exposed portion exposed from the body portion.
