Abstract
A lens includes an optical portion and a flange portion. The optical portion has a greater length along a first axis direction than a second axis direction, and the first axis direction and the second axis direction are perpendicular to an optical axis and perpendicular to each other. A flange portion extending along the first axis direction includes a first inclined portion connected to a first surface of the optical portion and a second inclined portion connected to a second surface of the optical portion. The second inclined portion protrudes in an optical axis direction, relative to the second surface of the optical portion, in an area in which the second inclined portion is connected to the second surface of the optical portion. A light absorption layer is disposed in the area in which the second inclined portion is connected to the second surface of the optical portion.
