Abstract: An optical module includes: a mirror unit; and a magnet unit including first, second, and third magnets arranged along a first direction. The mirror unit is disposed on the magnet unit in a second direction perpendicular to the first direction. A width of the first magnet is equal to or more than widths of the second and third magnets. An upper surface of the first magnet is located on a mirror unit side with respect to upper surfaces of the second and third magnets in the second direction, or is located at the same position as one of the upper surfaces of the second and third magnets and on the mirror unit side with respect to the other of the upper surfaces of the second and third magnets in the second direction. The mirror unit is fixed to at least the upper surface of the first magnet.

Abstract: A mirror unit includes an optical scanning device, a frame member, and a window member. The frame member includes first and second wall portions facing each other in an X-axis direction. The first wall portion is higher than the second wall portion. The 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 of the optical scanning device. In a cross-section parallel to the X-axis direction, the first wall portion is separated from a first line passing through a first end at a side of the first wall portion in the mirror surface and a first corner portion formed at the side of the first wall portion by an outer surface opposite to the frame member and a first side surface in the window member.

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.
