Abstract

A camera module disclosed to an embodiment includes a lens barrel; and a lens spacer disposed in the lens barrel. The lens spacer includes an opening portion penetrating an upper surface and a lower surface thereof, and a shape of an upper region of the opening portion is different from a shape of a lower region of the opening portion. The upper region of the opening portion comprises a first inner periphery having a curved shape, a second inner periphery having a curved shape and facing the first inner periphery in a first direction, and a third inner periphery connecting one-side ends of the first and second inner peripheries and having a straight-line shape, and a fourth inner periphery connecting the other-side ends of the first and second inner peripheries, which are opposite to the one-side ends thereof, having a straight-line shape, and facing the third inner periphery in a second direction. The lower region of the opening portion may have a circular shape.
