    Abstract: In an optical device, an elastic support unit includes a pair of levers which face in a second direction perpendicular to a first direction, a pair of first torsion support portions which are connected between the levers and the base, a pair of second torsion support portions which are connected between the pair of levers and the movable unit, and a first link member that bridges the levers. The levers and the first link member define a light passage opening. Each of connection positions between the levers and the first torsion support portions is located on a side opposite to the movable unit with respect to the center of the light passage opening in a third direction perpendicular to the first direction and the second direction. A maximum width of the light passage opening in the second direction is defined by a gap between the levers in the second direction.

    Abstract: A method of manufacturing an optical interferometer includes a first step of forming a first semiconductor portion for a beam splitter and a second semiconductor portion for a movable mirror on a main surface of a support substrate and a first insulating layer formed on the main surface, a second step of disposing a first wall portion between a first side surface of the first semiconductor portion and a second side surface in the second semiconductor portion, and a third step of forming a mirror surface in the second semiconductor portion by forming a first metal film on the second side surface using a shadow mask. In the third step, the first side surface is masked by the mask portion and the first wall portion and the first metal film is formed in a state in which the second side portion is exposed from an opening portion.
