Abstract
The present technology relates to a solid-state image sensing device and an electronic device for reducing noises. The solid-state image sensing device includes a photoelectric conversion unit, a charge holding unit for holding charges transferred from the photoelectric conversion unit, a first transfer transistor for transferring charges from the photoelectric conversion unit to the charge holding unit, and a light blocking part including a first light blocking part and a second light blocking part, in which the first light blocking part is arranged between a second surface opposite to a first surface as a light receiving surface of the photoelectric conversion unit and the charge holding unit, and covers the second surface, and is formed with a first opening, and the second light blocking part surrounds the side surface of the photoelectric conversion unit.
