Abstract
The rotation angle detection device includes: a magnet; a magnetic detection element disposed on the one side in the axial direction relative to the magnet with a gap interposed between the magnetic detection element and the magnet; and a shield. The shield is disposed at a location in the axial direction between a location in the axial direction of a wire member allowing current to flow therethrough and a location in the axial direction of the magnetic detection element, is disposed radially outward of the magnet as seen in the axial direction, and has a portion that overlaps with the wire member as seen in the axial direction. The wire member is disposed at a location in the axial direction that is closer to the magnet than the magnetic detection element is, and is disposed radially outward of the magnet as seen in the axial direction.
