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 ferromagnetic member provided to the movable plate; and a drive section configured to generate electromagnetic force between the drive section and the ferromagnetic member to thereby swing the movable plate, wherein a portion of the drive section, included in the distribution range of the light, is formed of a surface having a normal vector with which the light is reflected to outside of a predetermined range.
