Abstract
Solid-state imaging device of the present invention is a backside-illumination-type solid-state imaging device including wiring layer formed on first surface side of semiconductor substrate; and light receiving section that photoelectrically converts light incident from second surface side that is opposite from first surface side, wherein spontaneous polarization film formed of a material having spontaneous polarization is formed on a light receiving surface of light receiving section. Accordingly, a hole accumulation layer can be formed on the light receiving surface of light receiving section, and a dark current can be suppressed.
