Claim:
1. An image sensor, comprising: a plurality of first photoelectric conversion elements that receive a first light having entered a first surface of a semiconductor substrate through an image forming optical system and a plurality of second photoelectric conversion elements that receive a second light having entered the first surface of the semiconductor substrate through the image forming optical systems; a read circuit outputting signals, which is formed on a second surface of the semiconductor substrate opposite to the first surface; an on-chip lens formed at a position set apart from the first and second photoelectric conversion elements; a barrier member that is disposed parallel to an optical axis of the on-chip lens, between the on-chip lens and the first and second photoelectric conversion elements; a first separating area that is constituted with a type of semiconductor and that separates unit pixels from each other, each of the unit pixels including a first photoelectric conversion element among the plurality of first photoelectric conversion elements and a second photoelectric conversion element among the plurality of second photoelectric conversion elements; and a second separating area that is constituted with the type of semiconductor and that forms a boundary between the first and second photoelectric conversion elements included in the each of unit pixels.
