Abstract
A GMR angle sensor for vehicles includes a GMR element in which the element resistance is changed in response to an external magnetic field, lead conductors connected to either end of the GMR element, and a protective layer that seals the GMR element and the lead conductors, wherein the protective layer has a laminated structure including an oxidation-resistant inorganic film that ensures that the GMR element and the lead conductors are sufficiently insulated and a silicone-based organic film laminated on the inorganic film.
