Abstract
An image sensing apparatus includes an image sensing region where a plurality of pixels are two-dimensionally arrayed. Each pixel includes a photoelectric conversion unit, and a semiconductor region arranged below an element isolation region having an insulation film to isolate the photoelectric conversion unit from an adjacent pixel. The semiconductor region includes a plurality of diffusion layers. The offset amount of at least one diffusion layer in the semiconductor region with respect to the normal line is larger in a pixel arranged at the peripheral portion of the image sensing region than a pixel arranged at the center of the image sensing region.
