A scanning lens molded of resin includes: a lens portion having an elongate shape extending in a main scanning direction and having first and second longitudinal ends located opposite to and away from each other in the main scanning direction; and a flange portion extending outward in the main scanning direction from the first longitudinal end of the lens portion. The scanning lens has first and second sides located opposite to and away from each other in a sub-scanning direction, and a first protrusion is provided on the first side to protrude outward in the sub-scanning direction. The flange portion protrudes farther beyond the first longitudinal end in an optical axis direction of the lens portion. As viewed from the sub-scanning direction, the first protrusion is located at a position overlapping an interface between the lens portion and the flange portion.
