ABSTRACT:
A solid-state image sensing element has a photoelectric conversion element which converts incoming light into an electrical signal in accordance with an amount of the light, a microlens which is arranged on an incident surface, a light guide which is arranged between the photoelectric conversion element and the microlens, and an insulating interlayer which is arranged around the light guide. The solid-state image sensing element located at a distance (H) satisfies:H·DL·P<a·NHNL⁢⁢for⁢⁢0<a<1where L is the distance from an exit pupil of an image sensing optical system of an image sensing device, which mounts an image sensor formed by two-dimensionally arranging a plurality of the solid-state image sensing elements, H is the distance from a center of the image sensor to a position of the solid-state image sensing element on the image sensor, D is the height from the photoelectric conversion element to an apex of the microlens, P is the spacing between the plurality of solid-state image sensing elements, NHis the refractive index of the light guide, and NLis the refractive index of the insulating interlayer.
