Provided is a light-receiving element having a structure in which a floating diffusion region is surrounded by transfer gate electrodes in a single photoelectric conversion region constituting a pixel, the structure making it possible to improve optical symmetry and to extract light efficiently. The light-receiving element comprises: a photoelectric conversion region constituting a pixel; a floating diffusion region of a first electrical conductivity type provided on one main surface side of the photoelectric conversion region; and a plurality of transfer gate electrodes which are provided on the one main surface side of the photoelectric conversion region and are spaced apart from each other with a gate insulating film therebetween, the plurality of transfer gate electrodes being provided symmetrically about the floating diffusion region in a planar pattern.
