Abstract:
The invention provides a solid-state image sensor including a pixel having a plurality of photoelectric conversion portions and at least one waveguide arranged closer to a side of light incidence than the photoelectric conversion portions, wherein the waveguide has a core member and a cladding member formed of a medium having a refractive index lower than that of the core member, and wherein a layer formed of a medium having a refractive index lower than that of the core member of the waveguide is provided between the photoelectric conversion portions and the waveguide.
