Abstract
An imaging device and a manufacturing method of the imaging device are provided, which can lower the level of a dark current in an optical black pixel without forming a new layer such as a hydrogen diffusion preventing film. Both of an insulating layer over a photodiode arranged over an effective pixel region and an insulating layer over a photodiode arranged over an OB pixel region include silicon nitride, are formed of the same layer, and are coupled with each other.
