ABSTRACT:
A magnetic detection device of a NS detection type is provided. A magnetic detection device comprising a first series circuit, a second series circuit, and a third series circuit. At least one of a plurality of resistance elements forming the first series circuit includes a first magneto-resistance element using a magneto-resistance effect, of which an electric resistance varies with an external magnetic field of any one direction. At least one of a plurality of resistance elements forming the second series circuit includes a second magneto-resistance element using a magneto-resistance effect, of which an electric resistance varies with an external magnetic field of a direction apposite to the one direction.
