Abstract
The invention provides a magnetic detector that exerts no influence on detection accuracy of a magnetic movable body, being a detected body, even if relative positions of magnetic resistance elements and a magnet are out of alignment due to variation occurred in manufacturing process. A magnetic detector includes: a magnetic field detection part constructed of at least two magnetic resistance elements; a magnet for applying a magnetic field to the magnetic resistance elements; a magnetic movable body for changing the magnetic field that is generated by the magnet; and a processing circuit part for outputting a signal based on the change in resistance values of the magnetic resistance elements due to the change in the magnetic field; and in which a shape of the magnetic resistance elements is symmetric with respect to a point.
