Abstract:
An optical device includes: a movable plate disposed in a distribution range of light input from outside, and having a light reflecting surface adapted to reflect the light; a shaft member adapted to support the movable plate so that the movable plate can swing around a predetermined axis; a permanent magnet associated with the movable plate; and a coil generating an electromagnetic force to swing the movable plate. An upper surface of the coil is opposite to the permanent magnet, and the upper surface of the coil is formed as a plane having a predetermined angle with respect to a plane parallel to the movable plate.
