Abstract
The present invention includes a rotational angle sensor having a magnetic detection device. The magnetic detection device includes a sensing section that can detect a change of a magnetic field produced by at least two magnets attached to a rotary member. A housing member is molded integrally with the magnetic detection device and a support member. The support member may serves as a protective member for protecting at least the sensing section of the magnetic detection device or may serve as a positioning member configured to enable at least the sensing section to be positioned relative to the positioning member.
