Claim:
An image pickup element comprising: a light-receiving portion having an arrangement of photoelectric conversion portions, the arrangement being formed by disposing a plurality of first-direction arrays, each having photoelectric conversion portions arranged in a first direction with a gap maintained therebetween, in a second direction that is orthogonal to the first direction; and a plurality of lenses provided above the light-receiving portion, wherein a certain first-direction array in the matrix arrangement of photoelectric conversion portions is provided with a pair of photoelectric conversion portions that optically receive, via a pair of lenses, light beams passing through a pair of regions in an exit pupil of an optical system, the pair of regions being disposed in opposite directions from each other in the first direction, and wherein the pair of lenses is disposed such that light axes thereof extend through vicinities of edges of the pair of photoelectric conversion portions, the edges being the farthest edges from each other in the first direction.
