Abstract
There is provided an imaging device including a semiconductor substrate and a plurality of imaging elements that are arrayed in a matrix in a first direction and a second direction on the semiconductor substrate and perform photoelectric conversion on incident light. Each of the plurality of imaging elements includes a plurality of pixels that are provided in a predetermined unit region of the semiconductor substrate to be adjacent to each other and contains impurities of a first conductivity type, a separation section that separates the plurality of pixels, two first element separation walls that are provided along two first side surfaces extending in the second direction of the predetermined unit region to pierce through at least a part of the semiconductor substrate, and a first diffusion region provided in the semiconductor substrate around the first element separation wall and the separation section and containing impurities of a second conductivity type.
