Abstract
A displacement detection apparatus includes a magnetic field generator, a first soft magnetic body, a second soft magnetic body, and a magnetic detection element. The magnetic field generator extends along a plane orthogonal to a first direction and includes a first portion and a second portion. The first soft magnetic body entirely overlaps the first portion in the first direction. The second soft magnetic body entirely overlaps the second portion in the first direction. The magnetic detection element is disposed in a region between the first soft magnetic body and the second soft magnetic body, and is configured to be subjected to a magnetic field generated by the magnetic field generator. The magnetic field generator, the first soft magnetic body, and the second soft magnetic body are provided to be integrally rotatable, with respect to the magnetic detection element, around a rotation axis extending in the first direction.
