Abstract
A lens module includes a first lens, a second lens, a spacer, a seating part, and a protrusion part. The first lens includes a lens surface and a rib. The second lens is laminated on the first lens. The spacer maintains a predetermined interval between the first lens and the second lens. The seating part is disposed between the lens surface of the first lens and the rib and allows the spacer to be seated on the upper part of the first lens. The protrusion part includes a plurality of protrusions protruded from an undersurface of the spacer, which allow a height of the spacer seated on the seating part to change when the spacer is decentered.
