摘要：
A position detection device includes an electromagnetic conversion element and a magnetic field generator. The electromagnetic conversion element is arranged on a given plane. The magnetic field generator is arranged facing one side of the electromagnetic conversion element in a direction vertical to the given plane and generates a magnetic field covering the electromagnetic conversion element. A relative position between the electromagnetic conversion element and the magnetic field generator is detected when a relative displacement parallel to the given plane is made by the electromagnetic conversion element and the magnetic field generator based on an output signal of the electromagnetic conversion element. The magnetic field generator has an opposed face that tilts to the electromagnetic conversion element, and generates the magnetic field from the opposed face.
