Claims

[Scope of utility model registration request]

A magnetic detection device in which at least two magnetic resistors are provided on a substrate made of a magnetic material, and the substrate is attached to a pole end face of a magnet that applies a bias magnetic field to the magnetic resistors,
A magnetic detection device characterized in that a plate-like body made of a non-magnetic material is interposed between the substrate and the end face of the magnet.
