Abstract
A compact camera module is disclosed that is capable of preventing adhesion of dust to an image pickup device in the compact camera module. The compact camera module includes a lens unit including a lens and a lens holder holding the lens therein and an image pickup unit attached to the lens unit. The image pickup unit includes a circuit board, an image pickup device on the circuit board, a cover member arranged on the circuit board to cover the image pickup device, and an optical filter arranged with respect to the cover member to face the image pickup device. The image pickup device is disposed in a substantially closed space formed by the circuit board, the cover member, and the optical filter. After the image pickup device is mounted on the circuit board, the image pickup device is disposed in the substantially closed space, and therefore, the compact camera module can be assembled with no occurrence of dust adhesion to the image pickup device.
