要約
(EN)

Provided is an angle detection device capable of detecting the angle with high sensitivity by a very simple assembly process without requiring complicated processing. The angle detection device is provided with: a rotor (5) which is formed by a disk plate body produced from a magnetic substance having uniaxial magnetic anisotropy, the disk plate body rotating around a center point within the disk plate surface; a stator (3) which is provided to face the plate surface of the disk plate body of the rotor (5), has approximately the same external shape as that of the rotor, and is divided into a plurality of fan-shaped regions, and in which an exciting coil or a detection coil is wound along the outer periphery of each of the divided regions.
