Abstract
A back-illuminated solid-state imaging device includes a semiconductor substrate, a shift register, and a light-shielding film. The semiconductor substrate includes a light incident surface on the back side and a light receiving portion generating a charge in accordance with light incidence. The shift register is disposed on the side of a light-detective surface opposite to the light incident surface of the semiconductor substrate. The light-shielding film is disposed on the side of the light-detective surface of the semiconductor substrate. The light-shielding film includes an uneven surface opposing the light-detective surface.
