A camera module is provided to prevent impurity from flowing in an image sensor. An image sensor(120) has a light receiving part. The image sensor(120) is loaded in a board(110). An infrared blocking member(180) blocks an infrared ray in a beam which flows in the light receiving part of the image sensor(120). An optical unit is formed and installed as a hollow shape in an upper part of the board(110). A stepped difference part(133) at which the infrared blocking member(180) is mounted is mounted at an internal side of the optical unit. An impurity inflow preventing rib(135) for preventing impurity from flowing in the light receiving part of the image sensor(120) is formed in the stepped difference part(133) of the optical unit.
