Abstract
A rotation detecting device has various portions that are covered with a resin-molded section. After integrally molding the first and second cores 8 and 9, permanent magnet 10, and terminal 14 within a resin-molded section 11, a coil 12 is wound in a slot section 11a formed in the resin-molded section 11. Then, of the resin-molded section 11, the coil 12 and the terminal 14 are electrically connected in a recess formed at an outer periphery of the resin-molded section. Accordingly, the coil 12 is not liable to be damaged by a contact of a high-temperature, high-pressure resin during the molding process.
