A camera module for improving the efficiency of incident light by using a lens hole is provided to improve the efficiency of light inputted to an image sensor by implementing the lens hole in a square shape. Lens receives light image of a subject. An image sensor converts inputted optical image into electrical signal. A holder(50) includes infrared filter and lens hole(50a). An infrared filter blocks infrared ray inputted to the optical image. The lens is installed in the lens hole. The lens hole is formed in square shape.
