摘要：
Provided is a solid-state imaging device including a first photoelectric-conversion-portion selectively receiving a first wavelength light in incident light and performing photoelectric conversion; and a second photoelectric-conversion-portion selectively receiving a second wavelength light which is shorter than the first wavelength, wherein the first photoelectric-conversion-portion is laminated above the second photoelectric-conversion-portion in an imaging area of a substrate so that the second photoelectric-conversion-portion receives the light transmitting the first photoelectric-conversion-portion, wherein a transmitting portion is formed in the first photoelectric-conversion-portion so that the second wavelength light transmits the second photoelectric-conversion-portion more than other portions, and wherein the transmitting portion is formed to include a portion satisfying the following Equation within a width D defined in the direction of the imaging area, a refraction index n of a peripheral portion of the transmitting portion, and the longest wavelength λc of the second wavelength range selectively photoelectrically-converted in the second photoelectric-conversion-portion: λc/n≦2D
