Abstract
An optical scanner includes: a movable plate which includes a light reflection unit; a first torsion bar which oscillatably supports the movable plate around a first axis; a first displacement member which is connected to the first torsion bar; a second torsion bar which oscillatably supports the first displacement member around a second axis; a second displacement member which is connected to the second torsion bar; and an actuator which is installed on the second displacement member and applies a displacement to the second displacement member so as to apply torsional deformation and bending deformation to the second torsion bar, in which the first displacement member includes a frame member surrounding the movable plate, and a damper which has a smaller thickness than that of the frame member and extends in a direction intersecting with a direction in which the second torsion bar extends from the frame member.
