Abstract: The present invention relates to a camera module comprising: a lens part; a lens holder supporting the lens part while surrounding the same; a PCB assembly processing light input through the lens part into an electrical signal; and a shield can having an internal space in which the PCB assembly is disposed, wherein the PCB assembly comprises: a plurality of PCBs having circuits mounted thereon; and a flexible connecting part electrically connecting the plurality of PCBs and comprising a conductive layer in which a conductive material is disposed, and the shield can has an avoidance part formed in a position corresponding to the connecting part. According to the present invention, a pattern is formed on a conductive layer of a flexible printed circuit board so that it is possible to prevent cracks and tearing and to reduce a defect in the product at the same time even though the flexible printed circuit board is bent and subjected to a bending force, thereby enhancing the reliability of the product.
