Abstract
A solid-state imaging device includes a pixel region in which shared pixels which share pixel transistors in a plurality of photoelectric conversion portions are two-dimensionally arranged. The shared pixel transistors are divisionally arranged in a column direction of the shared pixels, the pixel transistors shared between neighboring shared pixels are arranged so as to be horizontally reversed or/and vertically crossed, and connection wirings connected to a floating diffusion portion, a source of a reset transistor and a gate of an amplification transistor in the shared pixels are arranged along the column direction.
