Abstract: An optical device includes a support portion, a first movable portion having an optical surface, a second movable portion having a frame shape and surrounding the first movable portion, a first coupling portion coupling the first movable portion and the second movable portion to each other, a second coupling portion coupling the second movable portion and the support portion to each other, and a softening member which has a softening characteristic and to which stress is applied when the first movable portion swings around a first axis. When viewed in a direction perpendicular to the optical surface, the softening member is provided to a portion of the second movable portion, the portion extending between a drive element and the first coupling portion, and is not electrically connected to an outside.

Abstract: A mirror device includes a support portion, a movable portion, and a pair of torsion bars disposed on both sides of the movable portion on a first axis. The movable portion includes a frame-shaped frame connected to the pair of torsion bars and a mirror unit disposed inside the frame. The mirror unit is connected to the frame in each of a pair of connection regions located on both sides of the mirror unit in a direction parallel to a second axis. A region other than the pair of connection regions in a region between the mirror unit and the frame is a space. An outer edge of the mirror unit and an inner edge of the frame are connected to each other so that a curvature in each of the pair of connection regions is continuous when viewed from a direction perpendicular to the first and the second axes.
