At least any one of the plurality of pixels include: a photoelectric conversion unit including first and second photoelectric conversion elements; a first sub-lens formed over the first photoelectric conversion element, and having a vertex out of a central axis of the first photoelectric conversion element; a second sub-lens formed over the second photoelectric conversion element, and having a vertex out of a central axis of the second photoelectric conversion element; and a microlens formed over the photoelectric conversion element so as to overlap the first and second sub-lenses. The first sub-lens is symmetrical with the second sub-lens, based on a boundary surface between the first and second photoelectric conversion elements.
