Abstract
A solid image pick-up element comprises a semiconductor substrate, a photoelectric transfer region formed on the substrate, and an optical black region formed on the substrate. Each of the photoelectric transfer region and the optical black region includes a plurality of regularly arrayed light receiving units. A shielding film is formed on the light receiving units of the optical black region and is covered with a shielding layer. Preferably, the shielding film comprises three color filters in red, green and blue. Even if the shielding film causes light leakage, the shielding layer makes light damp, thereby reducing the occurrence of light leakage.
