Optical device

An optical device comprising:

• 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 including a linear portion that extends along a first axis and is connected to the first movable portion, and coupling the first movable portion and the second movable portion to each other so as for the first movable portion to be swingable around the first axis;
• a second coupling portion coupling the second movable portion and the support portion to each other;
• a drive element provided to the second movable portion and electrically connected to an outside;
• and
• a softening member which has a softening characteristic and to which stress is applied when the first movable portion swings around the first axis, the softening member being a member different from the second movable portion and formed by material different from material of the second movable portion,
• wherein the softening member is disposed in a groove formed in the second movable portion or on a surface of the second movable portion and when viewed in a direction perpendicular to the optical surface, the softening member is provided to a portion of the second movable portion, extending between the drive element and the linear portion, and is not electrically connected to the outside.
