Abstract
An optical device includes an optical device including, a movable frame configured to hold an optical member, and a coupling frame to be coupled to the movable frame via an oscillation axis, and a stationary frame to which the coupling frame is fixed via a vibration absorbing member. The stationary frame has a shaft part to which the vibration absorbing member is attached, and a first surface and a second surface opposed to each other outside the shaft part, the coupling frame is disposed so as to be separated from the shaft part, the first surface, and the second surface with the vibration absorbing member, and a thickness of the vibration absorbing member existing between the coupling frame and the first surface and/or the second surface is thicker than a thickness of the vibration absorbing member existing between the coupling frame and the shaft part of the stationary frame.
