Abstract
In a solid-state image sensing device in which metallic wirings for supplying drive pulses to every transfer electrodes of vertical CCD registers are provided on the vertical CCD registers, the spacings between the metallic wirings are given mutually different sizes for an effective image sensing region and an optical black region. The shape of the step part beneath a light shielding film in the optical black region is improved, and the transmission of light is prevented. Accordingly, a correct black reference level can be obtained.
