Claim:
1. An image sensor, comprising: a pair of light receiving elements which is disposed for each of two-dimensionally aligned lenses and configured to receive light from a subject, wherein one of the light receiving elements are configured to output a pixel signal constituting one of captured images in a pair, and the other of the light receiving elements are configured to output a pixel signal constituting the other of the captured images in a pair, the captured images in a pair having a parallax for displaying a three-dimensional captured image of the subject; and a wiring layer disposed between the light receiving elements, wherein the wiring layer includes a plurality of wiring lines laminated spaced apart from one another, the wiring lines for transmitting an input signal or an output signal to and from the light receiving elements, wherein the lenses each have a curvature radius of r, the lenses are disposed at intervals of p, the lens and the distal surface of the wiring layer in the laminating direction has a medium disposed therebetween, the medium having an average refractive index of nav2, the wiring layer has a distance hb measured from the light receiving surface of the light receiving element to the distal surface of the wiring layer in the laminating direction, and the curvature radius r, the interval p, the average refractive index nav2, and the distance hb satisfying the relation of 1.4≦(1/p)·[r/(nav2−1)−hb]≦3.
