Abstract:
An imaging apparatus includes a micro lens, a second photoelectric conversion element that is located adjacent to a first photoelectric conversion element in a first direction, and a third photoelectric conversion element that is located adjacent to the first photoelectric conversion in a second direction intersecting with the first direction, wherein the height of a potential barrier produced at a region between the first and third photoelectric conversion elements against a signal charge is less than the height of a potential barrier produced at a region between the first and second photoelectric conversion elements against a signal charge.
