ABSTRACT:
A scanning lens is molded from resin. A lens part refracts a light beam which is scanned in a first direction of the lens part. The lens part defines an optical axis orthogonal to the first direction. The first end part is disposed adjacent to the lens part at one end in the first direction. A surface of the first end part defines an elevational difference that is orthogonal to a second direction, which is orthogonal to both the optical axis and the first direction. The elevational difference facilitates positioning of the scanning lens in the second direction.
