Abstract
A back-side illuminated imaging device includes a substrate including a photoelectric conversion region, a contact plug connecting a wiring layer and the substrate, and a capacitive element including a first metal electrode and a second metal electrode disposed between the first metal electrode and the substrate. A distance between the second metal electrode and the substrate is shorter than a length of the contact plug. The second metal electrode overlaps at least a part of the photoelectric conversion region in a planar view with respect to a main surface of the substrate.
