Abstract
An angle detection apparatus includes a magnetic detection element, a magnetic field generator, and a first magnetic shield. The magnetic field generator is magnetized along a first direction and generates a magnetic field to be applied to the magnetic detection element. The first magnetic shield surrounds the magnetic detection element along a plane orthogonal to the first direction. The magnetic field generator and the magnetic detection element are rotatable relative to each other around a rotation axis along the first direction.
