Abstract
A position detection magnet capable of improving the linearity of position detection with a simple and compact configuration is provided. The position detection magnet bipolarly magnetized includes at least three or more convex portions. The at least three or more convex portions are arranged in a row on one surface of surfaces parallel to a magnetization direction of the position detection magnet. The at least three or more convex portions are made of the same material as the position detection magnet and are magnetized in the same direction as the position detection magnet. An angle formed by an arrangement direction of the at least three or more convex portions and the magnetization direction is not perpendicular.
