Abstract
An optical device includes an elastic support portion which includes a torsion bar extending in a second direction perpendicular to a first direction and a nonlinearity relaxation spring connected between the torsion bar and a movable portion. The nonlinearity relaxation spring is configured so that a deformation amount of the nonlinearity relaxation spring around the second direction is smaller than a deformation amount of the torsion bar around the second direction and a deformation amount of the nonlinearity relaxation spring in a third direction perpendicular to the first direction and the second direction is larger than a deformation amount of the torsion bar in the third direction while the movable portion moves in the first direction. A first comb finger of a first comb electrode and a second comb finger of a second comb electrode which are adjacent to each other face each other in the second direction.
