Claim 16:
17. A position detection device comprising:
a magnet configured to generate a magnetic field to be detected; and
a magnetic sensor configured to detect the magnetic field to be detected and generate a detection value corresponding to a relative position of the magnet with respect to the magnetic sensor, the magnetic sensor including:
a magnetoresistive element including a first magnetic layer having first magnetization that can change in direction with a direction of the magnetic field to be detected received by the magnetoresistive element within a reference plane; and
a substrate that supports the magnetoresistive element, the substrate including a main surface including a flat surface, and a slope oblique to the main surface, the magnetoresistive element being located on the slope, the reference plane being parallel to the slope,

wherein the relative position of the magnet with respect to the magnetic sensor can change so that a predetermined point in the magnet moves within a linear range of movement,
the range of movement lies in a vertical plane perpendicular to the main surface,
the magnet is magnetized in a direction parallel to the vertical plane, and
the reference plane is oblique to the vertical plane.
