More Information
Summary:An image pickup element includes: a photoelectric conversion section; a wavelength selection section formed closer to an incident side of light than said photoelectric conversion section, for transmitting light in a predetermined wavelength range; a first area having a predetermined refractive index and being formed closer to the incident side of light than said wavelength selection section; and a second area having a predetermined refractive index and being formed closer to the incident side of light than said first area wherein the refractive index of said first area is higher than the refractive index of said second area.
