description	A lens unit has a first lens barrel including an annular accommodating portion which accommodates an outer peripheral-edge portion of a lens, a second lens barrel which accommodates a lens and is held on an inner peripheral side of the first lens barrel, and a first O-ring. The lens has an end surface facing the image side on an outer peripheral side of a lens surface. An accommodating portion includes a support surface facing the end surface of the lens on an outer peripheral side of the second lens barrel from the image side. The lens includes an annular contact portion in surface contact with the end surface of the lens on an inner peripheral side of the support surface. The first O-ring is compressed between the lens and the support surface in an optical axis direction.
