Abstract
An optical scanning device includes a reflector, a rotator, a first torsion beam and a second torsion beam, a first support part, a second support part, a first elastic layer, and a second elastic layer. The first elastic layer is superposed on the first torsion beam. The second elastic layer is superposed on the second torsion beam. A vertical dimension of an active layer is smaller than a horizontal dimension of the active layer in a cross section orthogonal to a direction in which the rotator is interposed between the first torsion beam and the second torsion beam. A material of the first elastic layer and the second elastic layer is higher in fatigue life than metal.
