Abstract:
A position detection device includes a first magnetic field generation unit for generating a first magnetic field, a second magnetic field generation unit for generating a second magnetic field, and a magnetic sensor. The position of the second magnetic field generation unit relative to the first magnetic field generation unit is variable. The magnetic sensor detects the direction of a target magnetic field at a detection position in a reference plane. The target magnetic field is a composite magnetic field of first and second magnetic field components which are respective components of the first and second magnetic fields parallel to the reference plane. The magnetic sensor includes a magnetoresistive element including a free layer and a magnetization pinned layer. In the reference plane, two directions orthogonal to the magnetization direction of the magnetization pinned layer are each different from both of directions of the first and second magnetic field components.
