Claim:
1. An imaging device, comprising: a semiconductor layer having a first side that receives light from a light-incident side of the imaging device, and a second side opposite to the first side, the semiconductor layer including a photoelectric conversion element; a first film adjacent to the first side of the semiconductor layer; an insulating film at a side of the first film closest to the light-incident side; a light-shielding portion at a side of the insulating film closest to the light-incident side; and a second film on the first film and the light-shielding portion; wherein, the insulating film and the light-shielding portion are surrounded by the first film and the second film in a cross-section view, and a surface of the second film on the light-incident side has a convex shape when viewed from the light-incident side that corresponds with the light-shielding portion and the insulating film in the cross-section view.
