Patent ID: 8134361

Claim:
A magnetic sensor, comprising: a substrate; and a plurality of sensor bridge circuits each including a pair of magnetic field detectors and a pair of fixed resistors arranged on the substrate, the pair of the magnetic field detectors and the pair of the fixed resistors being connected to form a bridge circuit, each of the magnetic field detectors being formed of a magneto-resistance effect element, and magnetization directions of the magnetic field detectors intersect with each other in a three-dimensional manner, wherein the substrate has a plurality of inclined surfaces, and normal directions of the inclined surfaces intersect with each other in a three-dimensional manner, the pair of the magnetic field detectors in each of the sensor bridge circuits is arranged on the same inclined surface, and each one of the pair of fixed resistors in each of the sensor bridge circuits is respectively arranged on a different one of two inclined surfaces which are parallel to each other and different from the inclined surface on which the magnetic field detectors in the respective sensor bridge circuit are arranged.
