Angle detection device for vehicle mirrors

Disclosed are a mirror and an angle detection device that detects an inclined angle of a mirror surface of the mirror. A mirror includes a mirror surface, an actuator (100) for swiveling the mirror surface, at least one magnet (130) for changing its orientation by an angle according to a variation in an inclined angle of the mirror surface, and at least one signal output unit (118) for outputting a signal according to the inclined angle, based on the orientation of the magnet (130).
