Abstract: In a mirror unit, a first wall portion is higher than a second wall portion. A window member is disposed on a top surface of the first wall portion and a top surface of the second wall portion and is inclined with respect to a mirror surface. When any one of first to fourth wall portions is set as a first reference wall portion, in a cross-section perpendicular to the first reference wall portion, a first line passing through a first end at a side of the first reference wall portion in the mirror surface and a first corner portion formed at the side of the first reference wall portion by an outer surface and a first side surface in the window member intersects the first wall portion. A wiring portion includes a portion extending inside a base and leads outside a frame member.

Abstract: An actuator device includes: a support portion; a movable portion; a first connection portion connecting the movable portion to the support portion on a first axis so that the movable portion is swingable around the first axis; and a first wiring provided on the first connection portion. The first wiring includes a first main body formed of a metal material having a Vickers hardness of 50 HV or more. The first main body includes a first surface facing the first connection portion and a second surface other than the first surface. The second surface has a shape in which a curvature is continuous over the entire second surface in a cross-section perpendicular to an extension direction of the first wiring.

Abstract: An optical module includes a mirror unit having a movable mirror portion, a magnet portion configured to generate a magnetic field acting on the movable mirror portion, and a package accommodating the magnet portion. The magnet portion has a Halbach structure including a first magnet applied with a force in a first direction, and a second magnet applied with a force in a second direction. The package has a bottom walls portion, a side wall portion, and a restriction portion configured to restrict movement of the second magnet in the second direction. The movable mirror portion is disposed in a space formed by the restriction portion.
