Abstract
Provided is an imaging device () including: an imaging element (); and a semiconductor element () provided to be opposed to the imaging element and electrically coupled to the imaging element. The semiconductor element includes: a wiring region (A,A) provided in a middle portion and a peripheral region (B,B) outside the wiring region; a wiring layer () having a wiring line in the wiring region; a semiconductor substrate () opposed to the imaging element with the wiring layer interposed therebetween and having a first surface (Sa, Sc) and a second surface (Sb, Sd) in order from a side of the wiring layer; and a polishing adjustment section () including a material that is lower in polishing rate than a constituent material of the semiconductor substrate, the polishing adjustment section being disposed in at least a portion of the peripheral region and provided in a thickness direction of the semiconductor substrate from the second surface.
