Abstract
An imaging device according to an embodiment of the present disclosure includes: a first substrate including a sensor pixel that performs photoelectric conversion; a second substrate including a pixel circuit that outputs a pixel signal on a basis of electric charges outputted from the sensor pixel; and a third substrate including a processing circuit that performs signal processing on the pixel signal. The first substrate, the second substrate, and the third substrate are stacked in this order, and a concentration of electrically-conductive type impurities in a region on side of the first substrate is higher than a concentration of electrically-conductive type impurities in a region on side of the third substrate, in at least one or more semiconductor layers in which a field-effect transistor of the pixel circuit is provided.
