Abstract
A solid-state image sensor includes a plurality of pixels for focus detection, each of the pixels including a photoelectric converter arranged in a semiconductor substrate, a microlens, and a light blocking portion arranged between the semiconductor substrate and the microlens to cover part of the photoelectric converter. A face in the pixel, which is parallel to a surface of the semiconductor substrate and on which the light blocking portion is arranged, includes a first opening and a second opening in addition to the light blocking portion. The light blocking portion includes a separator that has a light blocking property and is arranged between the first opening and the second opening. The second opening is larger in area than the first opening, and the light blocking portion is larger in area than the first opening.
