1. An imaging device, comprising:
a plurality of pixels, each pixel comprises a stacked structure, the stacked structure comprises a first level layer and a second level layer on the first level layer, a photoelectric conversion unit formation region is arranged on the first level layer, and a plurality of electric charge holding unit formation regions are arranged on the second level layer, wherein
the photoelectric conversion unit formation region comprises a photoelectric conversion unit configured to generate electric charge through photoelectric conversion, the electric charge corresponding to an amount of received light,
the photoelectric conversion unit formation region has a first planar shape in a plane extending in a first direction and a second direction, the first direction and the second direction being orthogonal to each other, and the first planar shape having a first aspect ratio, and
an electric charge holding unit formation region of the plurality of electric charge holding unit formation regions comprises:
an electric charge holding unit configured to hold the electric charge,
an electric charge transfer unit configured to transfer the electric charge, and
a discharge unit configured to discharge the electric charge to outside, wherein
the electric charge holding unit formation region has a second planar shape in the plane, and the second planar shape corresponds to a second aspect ratio different from the first aspect ratio,
at least two of the plurality of electric charge holding unit formation regions are disposed for the photoelectric conversion unit formation region in the first direction,
a first longitudinal direction of the photoelectric conversion unit formation region and a second longitudinal direction of the electric charge holding unit formation region match or are orthogonal to each other, and
the first aspect ratio is 1 and the second aspect ratio is 4.
