## Abstract

An electronic device is provided that includes a camera module that receives external light through a portion of a surface of the electronic device. The camera module includes a camera housing having an image sensor disposed on a bottom surface of the camera housing. The camera module also includes and a lens assembly. At least a portion of the lens assembly is disposed in the camera housing. The lens assembly includes a first lens, a second lens, and a spacer disposed between the first lens and the second lens. The spacer has an opening area formed therein. An optical axis passes through the opening area. The spacer is formed such that a first inner surface of the opening area and a second inner surface of the opening area are parallel to each other in a cross-sectional view that includes the optical axis.
