Abstract
A solid-state imaging device includes blue photoelectric conversion elements, green photoelectric conversion elements, red photoelectric conversion elements, infrared photoelectric conversion elements, and an infrared cut filter (IRCF) is layered on the blue photoelectric conversion elements, the green photoelectric conversion elements, and the red photoelectric conversion elements with a uniform film thickness. Color filters that respectively transmit the blue light, the green light, and the red light are layered on the IRCF so as to correspond with the blue photoelectric conversion elements, the green photoelectric conversion elements, and the red photoelectric conversion elements. A visible-light shielding filter is layered on the infrared photoelectric conversion elements. An ultraviolet cut filter layered between the photoelectric conversion elements other than the infrared photoelectric conversion elements and the IRCF, and between the infrared photoelectric conversion elements and the visible-light shielding filter with a uniform film thickness.
