Abstract
An optical device includes a support portion, a movable portion; and a pair of torsion bars. An optical function portion is provided on one surface of the movable portion and a rib portion is provided on the other surface of the movable portion. The rib portion includes eight extending portions of first to eighth extending portions. When setting directions in which the first to eighth extending portions extend as first to eighth extending directions respectively, and setting an angle between the first and second extending directions as a first angle, an angle between the third and fourth extending directions as a second angle, an angle between the fifth and sixth extending directions as a third angle, and an angle between the seventh and eighth extending directions as a fourth angle, each of the first and second angle is larger than each of the third and fourth angle.
