A photoelectric conversion device includes a pixel area, the pixel area including a plurality of pixels arranged in a matrix, each pixel comprising a photoelectric conversion portion, a floating diffusion, and a transfer gate, the transfer gate controlling transfer of charges generated in the photoelectric conversion portion to the floating diffusion. The photoelectric conversion portion is shifted relatively to the transfer gate depending on a position thereof in the pixel area. The shifting direction is a direction perpendicular to a charge transfer direction from the photoelectric conversion portion to the floating diffusion.
